Jethro Tull “Aqualung” released 50 years ago today, March 19th, 1971. The band’s fourth album went to #4 in the UK and to #7 in the US; it was their most successful and iconic album ever and made the best-of-all-time lists in many publications including Rolling Stone, The Village Voice, Guitarist, and Prog. The sometimes hard-rocking, sometimes twee flute folky prog rock album had two official singles: “Hymn 43″ (#91 US) and “Locomotive Breath” (which did not chart in ‘71 but went to #59 in the US when it was re-released in ‘76). Weirdly the title track, “Aqualung” was not a single (most likely due to its 6-minute-plus length) even though it’s one of their best-known songs (well, maybe that’s just me – I heard it…continue to hear it, actually, frequently on AOR radio stations). Besides those tracks, I also really like the acoustic ‘Elizabethan madrigal’ song “Mother Goose.”
