Starting as a blues band in the 1960’s, Jethro Tull thrust into the prog-rock genre with Aqualung, which Ian Anderson, to this day, denies was a cohesive concept album. This was followed by Thick as a Brick which Anderson states was a parody of the prog-rock concept album but which, to many prog-rock fans, epitomizes this musical construct. After disappointments over the next few releases, Jethro Tull came back in 1977 with quintessential British progressive rock in the form of Songs from the Wood, still considered one of their most musically successful albums. The band continued to pursue elements of the prog-rock style with its next effort, Heavy Horses, and really launched their career to new heights with this pair of albums. Like Kansas, the success of these two works led to the release of a double live album, Bursting Out, the following year.

The Jethro Tull concert presented here comes from the rarest of the rare in music collecting circles, a master tape soundboard recording. Sourced from a tape provided by a former roadie of the band, the recording was digitized and uploaded for torrenting in 2008. Remastering has corrected speed, tone and many tape flaws so that we can bring you an outstanding recording and performance by one of progressive rocks most enduring acts.

As noted above, the source for this recording was a digitised master tape of the soundboard. This show was found to be a mono recording so a stereo image was created. Speed analysis using live commercial and studio sources found a significant speed error which was then corrected. Because of recording levels, there is rare distortion during loud sections but most was minimised as much as possible.. Missing sections were repaired. Clicks and pops from the tape were repaired while bumps on stage were left unaltered. Dynamics were adjusted to smooth volume during monologues and to enhance the music sections. The show was then tracked using standard references.
