3) 8 piece ska band from Brisbane, Australia
4) a psytrance artist
5) Noise/Drone from San Francisco.
6) A Norwegian rock band with screamo elements. 1) The plan was for the Vanilla Fudge rhythm section of bassist Tim Bogert and drummer Carmine Appice to join with guitar god Jeff Beck and his singer Rod Stewart in a supergroup of sorts in the fall of 1969. The plan was derailed when Beck had an automobile accident that incapacitated him for the next 18 months.
