Clear was the third Spirit album, written largely in the wake of their work on the soundtrack to the 1968 film Model Shop. Several of the band members have said that they felt there wasn't enough time for developing the album after releasing two albums in 1968, recording a soundtrack and constantly touring, but a growing number of fans feel that it is one of their finest, if not the finest, album the group would ever make. Possibly because of the rushed work on the album, there is a larger reliance upon instrumental work and the jazz backgrounds of several members than any of their other albums, perhaps most exemplified by the three instrumental pieces penned by John Locke. It also features their sound gaining depth and sprawling out even more than it previously had, as they even attempt everything from the bluesy "So Little Time To Fly" to tightly constructed multi-part songs like "Dark Eyed Woman" and "New Dope In Town". Stylistically, "Clear" is a precursor to the band's next album, Twelve Dreams of Dr. Sardonicus.
