As a key architect of jazz-rock, Larry Coryell was crucial in elevating the role of guitar in the genre. After working with Chico Hamilton and Gary Burton in the ‘60s, he forged an expansive fusion of jazz improvisation, rock energy, and raga-inflected exploration, as heard on “Spaces (Infinite).” In the mid-'70s he briefly unplugged, but the folk and rock undercurrents on the delicately meditative “Julie la Belle” are unmistakable. For decades he toggled easily between the brooding swing heard on “Ghost Note” and the virtuosic fury of “Transvested Express,” conveying a probing sensibility that trumped any stylistic allegiance.
