In the late '60s and early '70s a power rock trio from Youngstown, Ohio called Glass Harp reached for the stars. A bare bones group in the tradition of Cream, The Jimi Hendrix Experience, and The James Gang, Glass Harp developed a signature progressive sound that allowed the members, collectively and individually, to stretch beyond the confines of standard form; breaks in songs for guitar, bass, flute, and drum solos were de riguere, as extended improvisations that would take the band's performances into the late hours.
These are photos from concerts where Glass Harp played, so they may be of other bands that played the concert as well.
