Recorded while Peter Frampton was still in the band, Performance: Rockin' the Fillmore captures an early performance by Humble Pie where Steve Marriot's lyricism and ideas where balanced by Frampton's searing lead guitar. This is hardly as engaging as As Safe Yesterday Is, which had studiocraft along with songcraft, but as a document of a band at a pivotal point in their existence, this is valuable and at times insightful.
