In the scheme of things, Last Concert Cafe keeps a pretty low profile within the local music scene, but their laid-back attitude toward marketing tends to obscure the fact that the tasty Tex-Mex cafe with the stage out back is one of the great grass-roots music venues in the city. However, everything that makes Last Concert unique, and such a cool place to see a show, will be front and center during this weekend’s Fall Harvest festival. The program calls for 12 bands over two days, most of them proffering one imaginative permutation of funk or another, and starting with the two mighty branches of the extended Meters family tree on board as headliners; Ivan Neville’s Dumpstaphunk (Saturday) and George Porter Jr. & the Runnin’ Pardners (Sunday). Sweetening the pot, as it were, are Austin’s Bourgeoise Mystics; NOLA futurists Naughty Professor; the hyper-creative youngsters in Paperwolf; local reggae stalwarts Idiginis; and lots more. Tickets are $30 per day — for a lot of music — or $50 for both, and don’t miss Friday’s free pre-party featuring three of Houston’s up-and-coming groove-meisters in Soul Creatures, Tightn’ Up and Now We Fly.
