50th anniversary edition of the British rock band's debut album. 'This Was', originally released on 25th October 1968, and was an album which made Jethro Tull one of the world's most successful progressive rock bands. On 2nd February 1968 the foursome played their first gig under the name Jethro Tull at London's legendary Marquee club. In June 1968, just before 'This Was' was recorded, the band began a residency at the same London club. The album was funded by the band as at the time of recording there was no record company contract in place with the band presuming, correctly, that a deal could be made after the album was finished.
