Lloyd Grant is a Jamaican musician best known for playing guitar in Metallica. Grant only played on the band's first demo "Hit the Lights" for the first pressing of the Metal Massacre compilation released in early 1982. Although this is the only recording of him in the band, his name is mentioned in the liner notes of Garage Inc as being lead guitarist.

K. J. Doughton's "Metallica Unbound" has this to say:

"Lars and James decided, with only hours to go before the 'Hit The Lights' demo was due for submission, that a second lead by a second guitarist would be essential. Lars knew a Jamaican guitarist named Lloyd Grant who was available. So, on the way to Hollywood's Bijou Studio where Brian Slagel was already finished mixing the other Metal Massacre tracks, the band screeched into Grant's driveway, lugged the four-track into his front room, and watched him churn a second lead break...

'I remember we had this four-track recorder,' explains Hetfield, recalling the last-minute struggle. 'It had tracks for drums, bass, guitar and vocals. Because there were no vocals in certain parts of the song, we could punch a lead in on the vocal track. I remember we wanted to get another solo on, so we stopped by Lloyd's house and hooked up some little fuckin' amp and just ripped through a solo. It was the first take. We went into the studio and that solo ended up on the record. It's a fuckin' great solo, man!'

The second and third pressings of Metal Massacre include a different recording of "Hit the Lights" with Dave Mustaine rather than Grant.
