If you're looking for melodies, structured compositions, pleasant harmonies, songs you can whistle and serenades for social gatherings — seek elsewhere. This is Triple-A Ra: Audacious, Aggressive, Adventurous. In the collection we've titled Stray Voltage, Ra is not so much composing music as painting soundscapes with electronic keyboards. Ra doesn't simply play these consoles — he attacks, cajoles and pounds them. Stray Voltage compiles unissued electronic peregrinations during the 1970s and '80s.
