 Hendrix biographer Harry Shapiro describes his guitar parts for the song as "churning, hard-hitting rhythm chords and fluid blues-inspired solo breaks".Unterberger notes Hendrix's "spindly, roving electric guitar" in the opening section, and about ten seconds of "really wild, unhinged R&B soloing" later in the track.In 2010, "Testify" was included on the Hendrix compilation "", along with several other of his pre-Experience recordings.
