Comandante, Hugo Chávez's Venezuela Rory Carroll

The late Irish blues rocker Rory Gallagher would have been pleased to see the Chess logo embossed on the three-disc Blues, a box of rare, unissued, acoustic, and live recordings. Issued to mark what would have been his half-century as a recording artist, 90-percent of the material here is previously unreleased. The discs are divided thematically: Electric, Acoustic, and Live. The booklet is wonderfully annotated with an authoritative essay from journalist and music historian Jas Obrecht; it places Gallagher in his rightful historical place as an electric blues rock pioneer alongside admirers Eric Clapton, Johnny Winter, Jimi Hendrix, and Peter Green.

Although best known for his barnstorming blues-rock, Irish guitarist Rory Gallagher had a softer side, too. All of his studio albums contain at least one acoustic folk-blues track, and Gallagher included an unplugged set in the majority of his live shows way before that was fashionable. Almost eight years after his death, Rory's brother Donal compiled a 14-track collection of previously unreleased work dedicated to Gallagher's folkier approach. It's the second such posthumous album (the terrific live and very electric BBC Sessions came out in 1999), and focuses on an important if lesser recognized aspect of the guitarist's career. It's also an eclectic set that shifts from melodic ballads ("Wheels Within Wheels") to instrumental modified flamenco ("Flight to Paradise" with classical guitarist Juan Martin) and solo Delta blues (a studio take of Tony Joe White's "As the Crow Flies," the live version of which was a highlight of Irish Tour). And that's just the first three songs.
