Jethro Tull – 20 Years Of Jethro Tull

Benefit was the album on which the Jethro Tull sound solidified around folk music, abandoning blues entirely. Beginning with the opening number, "With You There to Help Me," Anderson adopts his now-familiar, slightly mournful folksinger/sage persona, with a rather sardonic outlook on life and the world; his acoustic guitar carries the melody, joined by Martin Barre's electric instrument for the crescendos. This would be the model for much of the material on Aqualung and especially Thick as a Brick, although the acoustic/electric pairing would be executed more effectively on those albums.

Living in the Past is a double album quasi-compilation collection by Jethro Tull which contains album tracks, outtakes, the "Life Is A Long Song" EP, and all of their singles non-lp tracks except "Aeroplane", "Sunshine Day", "One For John Gee", "17" and the original United Kingdom version of "Teacher" (the United States single version, included in the US version of "Benefit", was included instead).

Rather than just give fans one live concert DVD to dig into, Jethro Tull deliver Around the World Live, a four-disc collection that spans over 30 years' worth of shows. Starting with a performance at the Isle of Wright festival in 1970 and going all the way forward to a 2005 performance in Lugano, Switzerland…

Jethro Tull was very much a blues band on their debut album, vaguely reminiscent of the Graham Bond Organization only more cohesive, and with greater commercial sense. The revelations about the group's roots on This Was – which was recorded during the summer of 1968 – can be astonishing, even 30 years after the fact. Original lead guitarist Mick Abrahams contributed to the songwriting and the singing, and his presence as a serious bluesman is felt throughout, often for the better: "Some Day the Sun Won't Shine for You," an Ian Anderson original that could just as easily be credited to Big Bill Broonzy or Robert Johnson; "Cat's Squirrel," Abrahams' big showcase, where he ventures into Eric Clapton territory; and "It's Breaking Me Up," which also features some pretty hot guitar from Abrahams.

Each era of rock music has had its own craftily marketed phenomenon – it was the "live album" in the '70s, "unplugged" recordings in the '90s, and since the late '80s through the present day, the "tribute album." But the early 21st century saw another addition – veteran bands revisiting classic albums and performing them in their entirety. Jethro Tull's most enduring release is largely agreed to be 1971's classic Aqualung, and in late 2004 Ian Anderson, Martin Barre, and their latest Tull mates dusted off the album once more in front of a small audience for XM Radio's Then Again Live series.
