I LOVE Rory. Honestly, who doesn't bust out a mean air guitar to "Tattoo'd Lady"? There's so much energy and life in his playing, and like you said - no frills, just ballsy blues rock. You never get a single pretentious vibe from Rory...he's up there to have the time of his life and just plain rock.
Criminally overlooked and makes blues guitarists like Clapton look like sissypants.
I can't drive to Rory Gallagher...I'd get a ticket for sure.
