Which 1975 Isley Brothers song features a famous guitar riff by Ernie Isley?

The 1975 Isley Brothers song featuring Ernie Isley's famous guitar riff is “Fight the Power.” The track appeared on the group's album The Heat Is On and became one of their defining funk recordings.

Ernie Isley was inspired by contemporary news events during a 1975 recording session and helped write the song, with additional musical contributions from keyboardist Chris Jasper. The forceful lyrics criticize authority and social power, while Ernie's guitar, drums, and congas give the recording its hard-edged rhythmic drive.

Released in May 1975, “Fight the Power” reached No. 1 on the Billboard R&B chart and No. 4 on the Billboard Hot 100. Its controversial use of profanity was censored for radio broadcasts. The song is sometimes confused with Public Enemy's similarly titled 1989 anthem, which later interpolated its “fight the powers that be” lyric.
