As a fan of the band Naked City, Dunn contacted keyboardist Wayne Horvitz in Seattle who introduced him to Eyvind Kang.[1] Dunn received his first credit for a session with Eyvind Kang, resulting in the piece "5th NADE/Invisible Man" on the 7 NADEs album released in 1996.[8] His involvement resulted in a long-term friendship with Kang, through whom he met a number of musicians, mostly in the jazz-rock genre.[7] Dunn was later introduced to the engineer Mell Dettmer and together they founded Aleph Studios.[3]
