Katz, originally from Los Angeles, began his career as a backing musician for Rabbi Shlomo Carlebach, performing on several of his albums in the late 1980s and early 1990s.
[1] Shortly after Carlebach's death in 1994, Katz formed the band Reva L'Sheva with several fellow Carlebach-inspired musicians, including guitarist Lazer Lloyd and bassist Adam Wexler.
The first of these took place in Detroit, Michigan, where Reva L'Sheva and other Jewish musicians played for Orthodox, Reform, and Conservative congregations, as well as a show at the New Life Baptist Church where they were accompanied by a gospel choir.
The album, Biladecha Lo Avo ("I'm Not Going Without You"), was recorded with producer Gilad Vital and co-writer Roi Levi, both of Shotei Hanevuah, and was promoted with the single "Hodu".
[6] Katz toured in support of the album with a band that included Lior Shulman of Hatikva 6 on percussion, sharing the stage with artists like Hadag Nahash's Shaa'nan Streett and Teapacks' Kobi Oz.
