Sax, Keyboards, and Vocals One of the single most talented people in the band, Glen versatility and accomplishment at each instrument is nothing short of amazing. The honky-tonk is prevalent on piano and the gospel is heard on the organ. Glen's sectional alto sax performance is smooth and his solos rip. Meanwhile, he has the most incredible vocal range. The depth of classic baritone soul singers and the scream of any classic rocker, “G.T.” is a must see.
