[2] In 1979, Holmes, along with musicians Joey Ciotti and Ray Bailie, formed Platinum Blonde, a punk and new wave band.

[7] In 1996, Holmes, along with former Platinum Blonde drummer Sascha Tukatsch and musician Dave Barrett, formed a band called Vertigo that later became known as No.

[10] Described by C. J. O'Connor of the Toronto Star as "pre-inflatable-pig Pink Floyd, powered by Marshall/clothed by Galliano," the band's sound was inspired by the music of the late 1960–early 1970 London rock scene.

[13] The band was not finding any labels to take them on, so Holmes began to organize once-monthly club events, called "Orange Alert".

[14][16] In 2002 Holmes and Guy established the Mod Club Theatre in a venue that was previously a pool hall called Corner Pocket.

[17] Holmes deejayed at the club under the name DJ MRK and from 2003 to 2007 his Thursday night shows were broadcast live from 102.1 The Edge.

[17] The venue also hosted live performances by artists as Amy Winehouse, Muse, New Order, The Killers and Keane.

[17][18] In 2010, Holmes, Galli, and Steffler reunited and played their first Platinum Blonde reunion show at The Mod Club.

[19] Holmes, along with Galli, drummer Dan Todd and bassist Rob Laidlaw, released the Platinum Blonde album Now & Never in 2012.
