After veering sharply from the blues inluences of their debut, This Was, Jethro Tull's sound quickly coalesced around jazz-tinged English folk influences and the antics of frontman/flautist Ian Anderson. But it was guitarist Martin Barre's swaggering riff off the title track of the band's fourth album that would become Tull's indelibly clichéd trademark--and the band's entrée into a long reign as arena-rock perennials. But there's a lot more to Aqualung than the riffage of that cut and its cousins, "Cross-Eyed Mary" and "Locomotive Breath." In an era when pseudo-Christian spirituality was a de rigueur, if cheap, musical commodity (from the overblown operatics of Jesus Christ Superstar to one-hit pop wonders such as "Spirit in the Sky" and "Put Your Hand in the Hand"), Anderson and company openly challenged the value of organized religion with a thematic album savvy enough to layer its thought-provoking lyrics between heavy strata of FM-friendly guitar bedrock. A cliché, perhaps; a landmark, no doubt. And a record many maintain is still Tull's finest hour. --Jerry McCulley
