There is more than one artist going by the name "Muscle".
1. Muscle is a producer of primarily electronic music signed to Future City Records. His Soundcloud artist bio contains the following description: "I am electric flesh, I am the digital kiss. I live in another dimension made of iron and steel. My only goal is to create the ultimate soundtrack for the soul-crushing workout of the future.
I am MUSCLE." Debut EP "The Pump" was released 18th March 2014.
2. Muscle was formed (no pun intended) in 1990 and consisted of Alan Dollgener (vocals keyboards) and Michael Goglia (percussion, keyboards, guitar). Alan and Michael were both in the band Of A Mesh in NYC. When that band broke up, they relocated to Dallas because of the burgeoning music scene there. The music scene was short lived however. After many futile attempts to recruit additional members, they decided to go it alone with the help of a DAT recorder for live gigs. Muscle met producer David May through an ad and became part of the Cybortronik collective. Dollgener went on to produce a CD called Fish Dream by Reverb Sleep. He died in 1993. He was 33.
