Barrett was born in Buffalo, New York. He started his professional career in 1990 when he formed the band Solstice with drummer Alex Marquez and guitar player Dennis Muñoz. The band recorded a demo in 1991 produced by Jim Morris and signed a record deal with the German label SPV/Steamhammer. In 1992 they released their debut album entitled Solstice (the name changed to "The Sentencing" on some pressings). That same year, Barrett and Marquez decided to join Malevolent Creation after their previous drummer and second guitar player didn't show up to a rehearsal,[2] putting Solstice on hiatus.[3] They took part on the recording of Retribution and toured with the band.
In late 1994 right after Malevolent Creation recorded their third album,[4] Barrett formed the death metal band HatePlow with guitarist Phil Fasciana and late drummer "Crazy" Larry Hawke, both members of Malevolent Creation. Barrett was the original vocalist, the band eventually got Kyle Symons to join on vocals due to Barrett's commitment to Cannibal Corpse[5] Although HatePlow was intended initially as mere a fun side-project, the trio recorded a four-song demo that enjoyed a wide spread throughout the underground trading circuit. After his departure from Cannibal Corpse Barrett extended his commitment to Malevolent Creation & HatePlow and participated in the recording of the albums Everybody Dies and The Only Law Is Survival which came out in 1998 and 2000 respectively.[6] In 2004, he left HatePlow. The same year Barrett left, the "Moshpit Murder" compilation was released which features tracks recorded live during "The Only Law Is Survival" U.S tour with Stormtroopers Of Death in 2000, tracks from their 1996 demo, and one song from their 1999 demo that was done with a drum machine.
Collaborations and side-projects
Since the 2000s Barrett has made a few guest appearances, providing extra guitar playing for bands such as Eulogy, Hollenthon, Infernäl Mäjesty, Pro-Pain and Unearthed.[7] In 2005 Barrett joined in on the recording of the Roadrunner United album The All-Star Sessions where he played guitar on the tracks "Annihilation by the Hands of God" and "Constitution Down".[citation needed]
In 2019, Rob Barrett recorded with death metal band Deicide for a tribute album for the 40th anniversary of the Dayglo Abortions titled
"Fuck The World If It Can't Take a Joke".
The track recorded was "Inside My Head" from their 1985 release Feed Us a Fetus.[citation needed]
In the mid-2000s, Barrett planned on starting a hardcore band with J.C. Dwyer on drums and Jonathan Buske on bass. It is currently unknown if a name was decided or if any recordings exist.[8]
Equipment
Guitars
Barrett is currently endorsed by Dean Guitars and uses their custom guitars, mainly Cadillac's but also V's and Z's.[9] All of his guitars are equipped with either an EMG set or a Fishman Fluence set and are tuned to A# and G# Standard, he also tunes his guitars like the top 6 strings of a 7 string guitar. Around 2007 Dean Guitars produced a signature model in limited numbers called the Cadi-Kill. In the past Barrett used to play two Gibson Les Paul's, a Jackson Dinky, briefly a B.C. Rich Bich, a Custom ESP M-1, and a Charvel 475 that was also in Ace Ventura: Pet Detective, the Charvel featured stickers from bands such as Black Flag, Biohazard, Slapshot, Wasted Youth and Dead Kennedys. His Les Paul's are now only used for studio recording. He now uses Fishman Fluence pickups in his signature guitars.
Amplifiers
Like O'Brien, Barrett uses Mesa Boogie amplifiers, such as the Dual Rectifier (old 2 channel version), the Triple Rectifier and, more recently, Mark V. For cabinets, he uses Crate, Marshall and Mesa Boogie 4 x 12", which are loaded with Celestion Vintage 30 speakers. Before Mesa Boogie, Barrett used Crate and Marshall amplifiers.[10]
