“Gannon's record 'That's What' compares well with Smokin' at the Half Note (Verve, 1965) with Wes Montgomery and Wynton Kelly. Yes, it is that good. ...swept away by the sheer joy of hard swinging, yet seemingly effortless jazz and end up feeling refreshed, invigorated, and full of hope for the world... Gannon is one of those low-key masters from whom the phrases just flow. He does nothing extra—doesn't show off, just puts every note in its perfect place.”
“Gannon is to Vancouver what Ed Bickert is to Toronto, a high-water mark in the instrument’s modern tradition. He’s direct, earthy and a fabulous foil to Coon.”
“This latest release features veteran guitarists Bill Coon and Oliver Gannon in friendly conversation going through an enjoyable set of originals and bop standards. “Chi Chi”, in particular is a wonderful display of the two guitarists complementing each other at a boppish clip. Even more distinguishing are their ballads in duet form. “Polka Dots” and “Darn that Dream” are charming in their delicacy, and Tadd Dameron's “If You Could See Me Now” is achingly sweet.”
“...your go-to fix for Canadian jazz guitar. The two friends (Bill Coon and Oliver Gannon) seem to share a telepathic musical connection...”
“Too Much Guitar shows two prolific guitarists at their best. Bill Coon and Oliver Gannon are an imaginative duo who make their instruments sing in amazing new ways. Theirs is a conversation across the ages steeped in both the modernistic sounds of John Scofield and Bill Frisell as well as the traditional jazz sounds of Jim Hall and Wes Montgomery. …Harmonically pleasing, Too Much Guitar taps deep into the improvisational potential of the music without losing sight of its original structure.”
“Gannon is a thinking musician, with constantly flowing, fresh ideas.”
