Robert Earl Keen’s annual New Year’s Eve concerts are a staple on the Texas Country reveler’s schedule, so much so that this year’s Gruene Hall performance is already sold out. But the usual gaggle of “extra tickets” (check Craigslist, i.e.) will likely abound, promising entry for those who really want to get in. Free tamales and popcorn, with Champagne splits available for purchase. 8pm Wednesday, Gruene Hall, 1281 Gruene Rd., (830) 606-1281.
