When Zappa did his Chrismas shows in New York City in 1976, Ronnie Cuber was part of the horn section, playing baritone sax and clarinet. Recordings of this concert were used on "Zappa In New York" and on "Lather".
More recently, Ronnie Cuber teamed up with The Beets Brothers to record "Infra-Rae". The album got released on the Maxanter label.
