Willie Nelson, looking beatific, worked the crowd Monday night at the Austin Music Hall. Nelson massaged his trusty guitar Trigger like his recent bout with carpal tunnel syndrome was a distant memory, and astonished the three-quarter-full house by starting with "Living in the Promiseland" instead of "Whiskey River." His 90-minute set was marked by several sly segues "Me and Bobby McGee" into "Me & Paul," "Blue Eyes Crying in the Rain" into "Blue Skies," etc. and a mysterious beret-clad woman furiously painting a portrait of Nelson on the side of the stage. Because he's Willie Nelson, he didn't even throw in anything from new album It Always Will Be until almost the end.
