"The title track to AC/DC’s fourth studio album is pure statement of purpose: Bon Scott casts rock & roll as something passed down from the heavens (“Let there be light … sound … drums … geetah!“), and the rest of the band members tear into the hopped-up boogie-blues riffs and rhythms as if they are indeed doing God’s work. It’s a thrilling and, in true AC/DC fashion, often amusing six-minute roller-coaster ride that telegraphs the magic, mythology, and electricity of rock & roll as well as any song before or since. “Let There Be Rock” is also a show-stopping staple of the band’s live sets, with Angus Young’s solo spot often stretching upwards of 10 minutes as he thrashes his guitar and body around the stage. Things were seemingly just as intense in the studio, where, reportedly, Angus’ amp exploded during the recording of the song. But, recalled older brother and Let There Be Rock co-producer George Young, “There was no way we were going to stop a shit-hot performance for a technical reason like amps blowing up!” —R.B.  Rolling Stone
