Rossen “Chock Full” Nedelchev (Drums). Rossen Nedelchev is a professional drummer, producer and educator in New York City. He hails from Sofia, Bulgaria, and let me tell you, that’s a helluva cab fare. His jack-of-all-trades mentality extends to musical styles as well, being an in-demand session drummer in the worlds of pop, jazz, funk, jazz-funk, rhythm & blues, blues & rhythm, rhythm & rhythm, and bluesy jazz. Rossen is the band leader for the rhythm & rhythm band Alter View and runs The Jazz Playground, a jazz outreach program for stressed-out New York City children. He also plays drums in the NYC pop/electronic band The Qualia. Rossen produces for a variety of artists and has a graduate diploma in jazz performance from the Brooklyn Conservatory of Music. He dabbles in photography, long-distance running, and child-raising (O.K, that last one is more than a dabble).
