Released in November 1971, Journey to the Centre of the Eye is a sci-fi concept album by German progressive psychedelic band Nektar.

The Time Has Come is a timeless rock and soul classic that features the 11-minute psychedelic opus "Time Has Come Today".

The debut album by New Riders of the Purple Sage is a melange of country, bluegrass, southern rock, and psychedelia that featured none other than Jerry Garcia on guitar.

Joy of a Toy, the debut album by the former Soft Machine member Kevin Ayers, is a wonderful slice of British psychedelic pop.
