Career
Though he left Iron Butterfly after only one album due to internal tensions, his work was an influence in the band for most of their history, since his replacement Erik Brann made a conscious effort to imitate his playing. Weis later recounted "Erik Braunn replaced me in Iron Butterfly, and if I remember correctly, he bought a lot of my equipment, some of my clothes, they tried to clone me basically.."
Weis appeared on Iron Butterfly"s first two singles, "Don"t Look Down On Maine" and "Possession", and their debut LP Heavy. "Apricot Brandy", an instrumental he co-wrote with Rhinoceros keyboardist Michael Fonfara, reached Number.
46 on the Billboard Hot 100 and has been used as background music on a number of television shows.
In 1974 Weis performed lead guitar on Lou Reed"s Sally Can"t Dance album and continued his lead guitar duties on the subsequent world tour. In 1979 Weis appeared as the Band Leader and Guitarist of "The Rose Band" in the movie The Rose with Bette Midler.
In December 2006, his debut solo album, an instrumental smooth jazz effort titled Sweet Spot, was released on Marshmellow Records.
