4. Minimoog (1970)

The monophonic Minimoog revolutionised music one note at a time, putting the alien sounds of hitherto room-sized, wallet-busting synths into a more portable and affordable package. Synthesized bloops and squawks began to creep into the repertoire of everyone from Floyd to Zeppelin, then the proto-electro of Kraftwerk and Tangerine Dream. According to no less an authority than Rick Wakeman, the Minimoog “absolutely changed the face of music”.
