Timothy Blake (born 6 February 1952, in Shepherd's Bush, London) is an English keyboardist, synthesist, vocalist, and composer, who is known for working with Gong, Hawkwind and his synthesizer and light performances as Crystal Machine, with the French Light artist Patrice Warrener.

Blake met Daevid Allen at Marquee Studios, where the latter was recording his first solo album Banana Moon in 1971.

He appears on all three albums of the Radio Gnome Invisible trilogy; Flying Teapot, Angel's Egg, and You, in fact Blake is the only composer, apart from the Allen/Smyth partnership, to have written for all three of the "Trilogy" Albums, making him one of Gong's most important composers.

Later in 1979, Blake joined up with another noted "space rock" outfit, Hawkwind, the group he had helped to form 10 years before, for a short stint between 1979 and 1980 and has sporadically rejoined them on several occasions.

Since November 2007, Blake has been collaborating with Hawkwind full-time, performing on theremin and what he chooses to call "virtual lead guitar" .
