Hawkwind

Acid rock/metal band from 1970s. Their sounds often feature 12-string guitars, synths, and the "audio generator" which creates swooping, warbling noises in the background. Most of their music was created while they were on acid, but it is still classy. Their greatest songs include, "Silver Machine", "Seven By Seven", "Orgone Accumulator", "Magnu", "Sonic Attack", and "Levitation".
