Orenstein is the co-founder of the rock/soul band Infidels, and Alta Moda, and was previously associated with the bands Michaele Jordana and the Poles, among others.
As of 1996, Orenstein split his ties with I.R.S. Records / Capitol Records, and is now an independent, unsigned artist. Orenstein began creating music early in his life and cites his mother’s blues and jazz record collection and Jimi Hendrix as inspirations. After being involved with multiple rock and R&B bands in the 70s, Orenstein collaborated with singer Molly JohnsoninToronto and they began creating their own music under the moniker Alta Moda. Alta Moda's first album release was on the Epic label for CBS Records, and had some commercial success. In 1990 Orenstein and Johnson signed with Miles Copeland III’s I.R.S. Records. They recorded and released the first album as “Infidels”, which saw worldwide release and again some commercial success as well as a Juno Award in 1991. While still keeping a hand in songwriting and record production, Orenstein began composing for film in 1994, scoring “Steve Di Marco’s Spike of Love”. Orenstein continued to provide musical scores to film television productions and in 1999 formed the company Norman Orenstein Music Inc. which is based in Toronto, Ontario, Canada. Orenstein's musical score is featured in the 2008 release of George A. Romero's Diary of the Dead.
