SERIAN terbentuk pada tahun 2010 yang awal sekali hanya beranggotakan Kumz (Utsman Firmansyah) dan Vtank (noviar) sebagai gitaris, mereka sering menggarap lagu ber dua, (mengaransment) lagu lagu yg Kumz buat.

Sebelum SERIAN terbentuk mereka pernah memakai nama D’layla dan pada akhirnya nama tersebut berubah menjadi SERIAN sampai saat ini, nama SERIAN sendiri diambil dari ikan hias yang berjenis (cupang), inspirasi itu didapat ketika kumz sedang sharing dengan Bayu salah satu sahabatnya yang sesama musisi, sempat keluar dari ucapannya yaitu kayya band, itu pun Kumz pikirkan sambil mencari nama lain untuk band mereka, dan akhirnya nama SERIAN lah yang terpilih yang mereka anggap paling cocok enak diingat, didengar dan juga diucapkan.

Seiring berjalannya waktu mereka mencoba mencari player yang pas untuk menjadi personil SERIAN dari audisi sampai mencari di sosial media  yang sesuai dengan kriteria mereka butuhkan diantara nya pengisi gitar, bass, drum dan keyboard. walaupun pada akhirnya belum ada yang cocok dan sehati dalam menterjemahkan lagu yang Kumz buat, mereka berdua dengan Vtank, tidak akan pernah patah arang untuk terus mencari komposisi yang sesuai.

Pada waktu ketika Vtank pun memutuskan untuk tidak melanjutkan karir bermusiknya,Kumz sangat kehilangan, tapi itu adalah pilihan dan hak seseorang. yang terpenting bagi mereka berdua sama-sama saling mendukung.

Dan pada tahun 2013 bertemulah Kumz dengan Deni, dan Kumz menganggap sepertinya Deni orang yang Tuhan rencanakan untuk SERIAN, dia mampu memberikan sentuhan yang enak dilagu yang Kumz buat, dan mulailah SERIAN terbentuk formasi, setelah Deni dan Eskiy  terjadi proses rekaman lagu tersebut, dan mulailah Kumz mencari sosok yang tepat  untuk mencari posisi seorang drummer. seiring berjalannya waktu tanpa secara sengaja bertemulah Kumz dengan pak Alex (sound man dari Sandhy Sondoro) yang memperkenalkan Kumz dengan  Anton Widiastanto adalah (ex drummer  Sheila On 7) via telpon pada tahun 2015, dan akhirnya Kumz memutuskan untuk berangkat ke Yogyakarta untuk bertemu dan membicarakan masalah single dari SERIAN. Dan pada akhirnya mereka berempat lah yang memegang peran penting bersama SERIAN.

SERIAN Sering mengikuti festival musik, pengisi acara HUT RI, pengisi acara peduli musisi, pengisi acara konser amal, band pembuka KOIN Anniversary, band pengisi acara DIK DOANK, Agustusan in kampung, band pembuka RADJA event Indosat, band pengisi acara di Fakultas Fisip Ahmad Dahlan, perfom Cinere Mall musisi peduli musisi.

Lagu-lagu SERIAN  banyak mengambil liriK dari tentang percintaan, galau, senang, sedih, bahagia  dan kehidupan tentang curhatan dari sahabat-sahabatnya, ada beberapa lagu yang sudah  sering mereka bawakan di antaranya TUHAN TUMBUHKAN NYALIKU dan PATAH HATI.

“Industri musik boleh kedatangan banyak pemusik baru yang lebih segar pun tampan, Tapi bagi mereka, posisi dan lagu-lagu SERIAN telah menjadi suatu cerita yg berbeda di setiap kehidupan pendengarnya, dan kami takkan pernah merasa puas, dalam membuat karya-karya yang baik, dan berharap ini akan selamanya, sampai nanti waktunya Tuhan memanggil kami untuk kembali”. Dan itu adalah moto mereka untuk tetap fokus dan semangat di dunia musik Indonesia maupun Internasional.

Richard Denny Nahazon Nope, or better known as DENNY FRUST, surely is not a stranger in the Indonesian Reggae and Ska scene, and the man with both East Nusa Tenggara and East Java blood running in him is even dubbed as the Indonesian Prince of Ska by the masses. Denny Frust started his musical career in the mid 1990s in Surabaya and moments later set his eyes on Jakarta to set foot on a much broader and bigger musical realm. In 2009 Denny Frust joined and gained fame with the Jakarta based Ska band, MONKEY BOOTS. Together with Monkey Boots he released two albums, Big Monkey (2010) and Interaksi (2015), where most of the lyrics from both albums were written by Denny Frust.

However, in 2016 DENNY FRUST felt the need to create and to express himself independently from MONKEY BOOTS. He aimed for something grander. After parting ways with the band, Denny Frust released a mini album called Tiada Beban (2016) and received critical acclaim in the Indonesian music scene.

DENNY FRUST’s musical journey kept on reaching new heights and even opened new doors that enabled him to experiment more on his music. His music is not a joy for the Indonesian people’s ears only, but fans from various Southeast Asian countries such as Malaysia, Singapore and Vietnam flocked to attend his Tiada Beban mini album tour. DENNY FRUST even received the honours to open for the Jamaican Godfather of dance-hall reggae, Johnny Osbourne’s concert, in the Kilo Lounge, Singapore, on May 2017.

After completing his tours and promos for his mini album, on July 2017 DENNY FRUST launched his Full Length Album, Jangan Lupa Bahagia, the album consists of 10 songs, “You are My Home”, “Tersenyumlah”, “Tebarkan Kasih”, “Merindu”, “Make You Groovin”, “Keluargaku Semangatku”, “Janna Lupa Bahagia”, “Bunga yang Indah”, “Beri Wanna”, and “Datanglah Kepada-ku”, the last being one of the best hits-single from the album.

Each track from the album has different musical characters and colours that varies and are notably different that of the previous DENNY FRUST pieces. DENNY FRUST explores more and had other fellow musician friends involved to add more distinctive colours to his music. Lyrically speaking, DENNY FRUST entertains us with simple phrases with a Biblical feel that becomes his trademark in the storytelling of his experiences, feelings, ideas, and what he sees in everyday life in his surrounding neighbourhood.

The song “Datanglah Kepada-ku” is the first single from Jangan Lupa Bahagia for a good reason, it is for the listeners to get to know DENNY FRUST’s strength and trademark in writing Biblical nuanced lyrics in this album better. He tells a story of the journey of man in living everyday life undergoing obstacles, big and small ones alike. As a human being, we are to return to The Almighty, to confess and to give in, in order to find a solution or a way out from the problems faced in life. Because, “if your heart is clouded and heavy, come to Me (Him)”.

Sandhy’s love and passion for music started at a very young age. As soon as he graduated high school, at the age of 18 he left Jakarta for California to visit his uncle and stayed there for a while with dreams of launching his career as a performer.

Those dreams got put on hold when he had to go to Germany to study architecture. He first had to improve his German proficiency to be admitted at the university. During his time in Germany, Sandhy “changed” his last name from “Soendhoro” (new spelling : Sundhoro) to “Sondoro”, because many people had difficulties in pronouncing it. He also explained that Sondoro means “The Sound of Gold” in Latin. On his birth certificate and other official documents, his last name remains as “Soendhoro”.

Sandhy Sondoro’s music is influenced by American and British rock legends like the Beatles and Led Zeppelin. The power of his voice reminds us of Curtis Mayfield, Bobby at he is sometimes called the Ben Harper of Jakarta.

In Germany, Sandhy joined a band in his campus where they mostly did covers of Van Halen, Mr. Big or The Black Crowes, but they rarely appeared on the public stage. Later, he decided to find a job as he lived alone and needed to earn some income. He then got a job in a grocery store, but the passion and dreams for singing and playing the guitar was stronger than the drive to work in an office. On his bicycle back to his apartment, he saw a busker on the street and asked if he could join him.

The busker agreed, so Sandhy borrowed his friend’s guitar and started playing on the streets of Biberach an der Riss. They got 50 deutschemarks in an hour and shared the money.

They played three times a week before he decided to do it alone. He’ll do anything to get people’s attention to notice his music, said the big fan of Ray Charles.

In 1998, Sandhy moved back to Berlin and started singing and playing theguitar in bars, clubs and metros. His famous song “Down on the Streets”was inspired by his experiences in the Berlin metros. He also performed in famous theatres like the House of World Cultures in Berlin and some music festivals such as the Bode Mu- seum Isle Festival. In 2005, Sandhy performed in “Berlin for Asia” a charity concert for the 2004 Indian Ocean earthquake and tsunami victims. Sandhy then found a wider audience through Stefan Raab’s casting show, a popular segment within one of Germany’s most success- ful late night shows SSDSDSSWEMUGABRTLAD. Not long after releasing his first single “Down On The Streets”, on April 25, 2008 he published his debut album “Why Dont We”.
