This was the last album by the classic Humble Pie lineup featuring Peter Frampton, who quit shortly after the tour documented on PERFORMANCE--ROCKIN' THE FILLMORE. Frampton departed because of artistic differences with co-founder Steve Marriott--he felt that the acoustic semi-pop songs he favored were being crowded out by a reliance on Led Zeppelin-style guitar rock.
ROCK ON, however, is still reasonably split between the two styles. Highlights include Frampton's melodic and gospel-ish "Shine On," Marriott's Faces-style boogie "79th and Sunset" (featuring the immortal line "There'll be some dramas inside her pajamas tonight"), and a convincing version of Howlin' Wolf's "Rollin' Stone."
