Album DescriptionDigitally remastered two CD digipak edition of this 1977 album from the Deep Purple vocalist. Clear Air Turbulence was the second full length album by Ian Gillan Band, released in 1977. Instead of the Hard Rock/Heavy Metal sound of his former band, what we have here is a mix of Funk, Soul, R&B, Gospel, Jazz Fusion with just a bit of Hard Rock for good measure. This album illustrates Gillan's willingness to take some chances. Heavy Metal and Hard Rock are in short supply on this album, which employs no less than five horn players and shows that Gillan didn't want to be a headbanger 100% of the time. Metal Mind. 2009.
