Al Harlow

Vocals and Guitar

Born in Vancouver BC, Al “Harlow” Hawirko, began leading local Brit Invasion style bands in 1966. A displaced Mod in Vancouver’s psychedelic Retinal Circus scene, he studied the blues greats and moved to London England in the early ’70s. While recording his band “Harlow” in ’77, producer Bruce Fairbairn heard the results, and teamed Al up with ex-Seeds of Time bandmates to complete the PRiSM lineup. Eight albums, two Junos and five years of North American tours later, Al began lecturing in the Capilano University Music Dept. He currently tours PRiSM while gigging and recording locally.

Marc Gladstone

Keyboards, Vocals

Marc started his formal training at the age of seven and he was finished his Royal Conservatory training by age fifteen, scoring first class honours throughout.

After cutting his professional teeth with a few cover bands straight out of highschool, he landed the keyboard chair in Doug and the Slugs for the last seven years of that band, until the untimely passing of Doug Bennett.  He then joined Nick Gilder/Sweeney Todd as well as a short stint in the band Toronto.

He is now a highly sought after piano teacher in the Vancouver, BC area, as well as holding the keyboard position in a variety of bands: Google him and find Abandon Paris… Stone Poets… The Jardines… HEAD… stop by and say hi. He’d love to hear from you!

Marc joined Prism in 2010 and is actually a cousin to John Hall (original keyboardist for Prism), and his orchestral keyboard work is a perfect match for the Prism sound.

Gary Grace

Drums

Born into a family line of drummers, Gary Grace hails from Southern Ontario, now residing in Vancouver. He started playing at a young age under the guidance of his Father Doug Grace and older brother Danny Grace, furthering his studies under some of the worlds greatest drummers from Montreal, Toronto and New York, including Jim Petersak (Crane School of Music), Jim Chapin, Moe Slutsky, Dom Famularo, Ed Thigpen, and Joe Morello. 

Gary has performed many drum clinics, trading chops onstage with greats such as Marvin “Smitty” Smith, Virgil Donati, Tony Royster, Rodney Holmes and others. Gary has won multi-awards, most recently the 2009 Canadian National Championship for Roland V-Drums where he took first place in the Finals, opening the Montreal Drum Fest. He has recorded and toured with many top Canadian recording acts, devoting many years to Classic Rock band “Prism” where his showcase “On Fire” style of drumming is not to be missed!

Greg Cox

drumming at 10, was playing clubs by 16, and joined Steeler in 1978, later switching to guitar after a
wrist injury. When Steeler ended in 1993, he formed Playground Zone, a band still performing weekly

By 2015, Greg revived his Pink Floyd set into the acclaimed Pink 4Reud tribute, now a major concert

became the newest member of Canadian rock legends Prism.
