Viktor Benev was born in 1990 in Sofia, Bulgaria of a middle-class family.

At the age of six, he starts playing piano initiated in music by his mother, the pianist Lilyana Getova (1955-2014) and after a successful audition with Dobri Paliev (1928-1997), the founder of the percussion class in Bulgaria, in 1997, Benev officially enters the National Music School of Sofia "Lubomir Pipkov" in the percussion class of Dobri Paliev's successors and daughters Mariya Palieva and Iskra Palieva. He continues playing piano, but chooses percussion as his main discipline. In 1997, he wins his first "special prize" at the International Competition "The Music and the Earth" with the percussion ensemble "Snejinka".

During Benev's twelve years of studies, numerous European tours (notably with chamber ensembles and the CEI-Youth Classic Orchestra) and prizes from percussion competitions are to follow. The most notable being his winning 3 prizes on the same edition of "Pendim" in Plovdiv, Bulgaria in 2007 : 1st prize, special prize for vivid stage presence and the special prize of Tatiana Koleva and Pustjens Percussion Products. During the competition he also drew the attention of the percussionist, composer and educator Emmanuel Séjourné, who was at the moment presiding the jury and who, afterwards, invited Benev to continue his studies in the Conservatory of Strasbourg in 2009.

Around the same year of 2007, Benev was introduced to jazz and improvisation by his classmate and pianist Momchil Atanasoff. Benev had started improvising mostly on piano a few years back, but this encounter was a major influence on his decision to start learning jazz music theory and the language of improvisation.

In the summer of 2010, due to economic and personal reasons, Benev takes the initiative to return to Bulgaria and enrolls in the National Academy of Music "Prof. Pancho Vladigerov" jointly in the percussion class of Tatyana Karparova and in the theoretical department in the composition class of Velislav Zaimov.

In the two years that follow, he studies piano, harmony, counterpoint, classical compositional structures, arrangement and also forms, composes for and plays in various bands on numerous stages, festivals and concert halls.

After living in France, though, Benev's return in his native country does not diminish his multi-cultural and cross-border interests. Quite the contrary. He meets the Cuban percussionist Reidi Machado from the "Ku-Ku Band Orchestra" and takes lessons on Cuban music and rhythms. Soon after, he becomes part of the "De Fuego" salsa band, playing classic Cuban repertoire in dance clubs.

At the same period, in search of other melodic, rhythmical influences and traditions to be absorbed, he becomes the drummer of the band "SamBrasil" (later to be renamed briefly to "Marinheiros do Brasil") with his Brasilian friends and colleagues Dante Coutinho and Giovanny Conte, who are based in Sofia at the time.

Benev writes music for his own jazz bands in which he plays marimba and drums. He also plays with one of the most renowned Bulgarian jazz musicians such as Hristo Yotsov, Ventzislav Blagoev, Stoyan Yankoulov "Stundji", Vasil Parmakov and others. In 2010, he is awarded the "Best Participant" prize at the Master Class of the pianist and composer Milcho Leviev and vocalist Vicky Almazidu.

In the winter of 2012, during a brief trip to Paris, Benev would get acquainted to the Bulgarian artist bilyana furnadzhieva. He would definitively move to Paris in December of the same year.

In 2012, Parisian apartments being very restrictive in terms of noise and space, Benev bought a MalletKAT, an electric (midi) vibraphone. While in the beginning it was more of a practical solution for music training purposes, this instrument would slowly push him to deepen his research in music production and contemporary electronic music (genre, for which he had admiration since his teenage years). Not satisfied with the sounds available in the instrument, he would start using Ableton Live, creating his own sounds and learning about the art of sound engineering.

Later on, this interest would be further amplified by Benev's collaboration with the French sound engineer and producer Philippe Teissier du Cros on Crystal sound project's debut album in 2018.

In 2017, bilyana furnadzhieva shares her idea of a joint work combining visual art, literature, sculpture and electroacoustic music to Benev. This marks the foundation of Crystal sound project, the duo's base for artistic exploratory experimentations, which would soon become a major part of their own collaborative work.

With the financial support of Hélène Nguyen Thien, in 2018, Crystal sound project invites the singer Selma Savolainen and the double-bassist Jean Paul Celea in Philippe Teissier du Cros' studio in Paris and makes their first record "Crystal sound".

The experience of working with du Cros is so strong that Benev decides he would find a way to build his own recording studio, consacrate extensive periods of time to learn about sound engineering, would establish his own record label and become a producer for his own and Crystal sound project's records in the near future.
