Born in 1969 in Petah-Tikva, Israel, Asaf later moved to the town of Rehovot, where he spent his teens and early twenties. This was an influential move for Asaf, as it was here amongst the diverse cultural influences he found in Rehovot that Asaf began to show an interest in music and rhythm. In Rehovot he lived amongst people from North Africa, east and central Europe, and the Middle East. Living in Shaarayim, the Yemenite neighbourhood in Rehovot, Asaf was particularly drawn to Yemenite culture, music, and rhythms.
At the age of 12 Asaf began drum lessons, while also having a strong interest in playing electric bass. The music that influenced Asaf at the time still influences his writing and playing till this day; The Beatles, Police, Yes, Genesis, Mahavishnu Orchestra, Allan Holdsworth, and Weather Report to name a few.
1987 – 1990 Asaf did his compulsory national service. Out of the army in 1990, Asaf started his professional career as a musician playing with many different young Jazz-Rock, Kleizmer, world music, and Free Jazz bands. During that time he co-operated with Israel’s local Jazz/world luminaries such as Harold Rubin, Albert Beger, Yair Dlal and Eyal Sela. Many of those early projects where recorded and released by a pioneer Jazz record label in Israel called Jazzis (founded by Adam Baruch). Around those years Asaf started to write music but it wasn’t until 1995 when he formed his first trio that he found an outlet for his writing.
