Humble Pie's 1971 live album, Rockin' the Fillmore, has been expanded and will be re-released today (Tuesday) in a four-CD set put together by the band's surviving members, Peter Frampton and Jerry Shirley.

Rockin' the Fillmore: The Complete Recordings contains all four shows exactly as they were played on May 28th and 29th, 1971 at New York’s Fillmore East -- with no editing or re-sequencing. The seven tracks from the original album are joined here by 15 previously unissued performances, including the never-before-heard complete first set from May 28th.

In listening to it Frampton says, "It’s like a breath of fresh air... The beauty of it is that you get three other completely different performances of most of the songs. And it’s great to hear [singer] Steve Marriott’s banter from all of the shows."
