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
