Spirit's self-titled, experimental debut album was commercially successful[dubious– discuss], and garnered significant underground FM airtime. The album reached #31 on the Billboard LP charts.
The album was first published by Ode Records in 1968. It has since been reprinted by Sony, repackaged in compact-disc form and remastered from original analogue tapes.
In 1973, Epic released a two-disc LP repackage of Spirit and Clear entitled "Spirit".
The guitar riff that occurs about :43 into "Taurus" is said to have influenced Led Zeppelin's Jimmy Page in 'composing' his famous intro to "Stairway to Heaven". Led Zeppelin opened for Spirit on an American tour in 1968, and also borrowed the riff of "Fresh Garbage" during early live performances of the song 'As Long as I Have You'.
