Brent is a native of Winnipeg, Manitoba, Canada where he grew up with his parents Mervyn and Audrey Fitz and a sister, Brenda, who is also a professional musician.

[3] In 1985, Brent answered an ad for a teaching job at a local drum shop in Winnipeg, and despite being only 15 at the time, was hired based on his excelled musical ability and people skills.

Fitz got his professional start at age 15, playing in various Winnipeg clubs and outlying areas in a cover band named New Alliance.

After graduating high school, he formed the band Seventh Heaven with two local musicians and two Los Angeles natives that had recently relocated to Winnipeg.

In 1996, while attending the NAMM music trade show in Anaheim, California, connections to the city of Los Angeles within the band Seventh Heaven, allowed Fitz to have the opportunity to seek work in that market as a performer and session player.

[8] Working with previous Shake Naked vocalist Lenita Erickson later proved fruitful as Erickson's friend Bruce Kulick of Kiss fame invited Fitz to join him in a recording effort after first hearing him play piano, and later seeing him play drums at The Roxy in Hollywood, with former Duran Duran singer, Lamya .

[8] That band would become known as Union[9] and would also include John Corabi on vocals (formerly of The Scream and Mötley Crüe), James Hunting of David Lee Roth on bass, with Kulick on guitar.

In September 2000, Fitz briefly joined the Bulletboys on tour in support of their Best Of collection,[11] and recorded several new songs at Cherokee Studios in Los Angeles with famed Led Zeppelin producer, Andy Johns.

Fitz appeared on a second episode in June 2010, this time performing live with Bruce Kulick and Nick Simmons at The Cat Club in Hollywood, California.
