The only continuing member of the pioneering synthesizer group Tangerine Dream, Edgar Froese also proved to be one of the most ambitious in releasing solo albums alongside the voluminous output of the band. Considered a master of the Mellotron, the early keyboard device (made famous by the Moody Blues) that produced its sound through key-activated tape loops of actual recordings of orchestras, choirs and other acoustic sounds. Though it still drew from TD's trademark sequencer sound, Froese's solo recordings have a more direct and personal quality, and often feature his penchant for rock-style guitar work.
