1) The Andy Warhol Museum’s Sound Series features cutting-edge musical acts from around the world, and tonight’s performers are rising stars from the Montreal indie scene: The Barr Brothers, with their hypnotic, bluesy style of folk-rock-jazz eclecticism. Songs like “Half Crazy” feature a harp played by band member Sarah Page, who is nobody’s brother. Along with Andres Vial and actual brothers Andrew and Brad Barr, Page is part of a crew in which everybody sings and all but Brad (guitar) play multiple instruments—including those not normally used for music, as in the percussion section of “Lord I Just Can’t Keep From Cryin‘.” The Barr Brothers are touring in support of their new album Sleeping Operator. Tonight they’ll be joined on stage by a sneaky smooth operator, guest vocalist and instrumentalist Leif Vollebeck. 8 p.m. The Warhol, 117 Sandusky St., North Side.
2) George Orwell never knew what the year 1984 would bring: Apple introduced the Mac, Reagan was re-elected, Mark Zuckerberg was born, and Rob Reiner and friends released This Is Spinal Tap. To mark the 30th anniversary of that momentous event, the Three Rivers Film Festival is screening Spinal Tap tonight. The mockumentary about a made-up British band is hilarious because it’s so deadpan-serious, drily ripping the world of rock ‘n roll in scene after scene. (Whereas The Who had an exploding drum set, the Spinal Tap boys wistfully recall the loss of a drummer who exploded.) Actors Christopher Guest, Michael McKean, and Harry Shearer co-created the film with Reiner while also playing the band members—and if you haven’t seen Guest as the exquisitely addled guitarist Nigel Tufnel, why wait another 30 years? 9 p.m. Waterworks Cinemas, 930 Freeport Rd., O’Hara Township. (Also 8 p.m. Nov. 15 at Harris Theater, 809 Liberty Ave. Downtown.)
3) After this summer’s Jason Aldean and Toby Keith concerts, our “Southern” (PA) town of Pittsburgh is in the midst of a slack country music period. What’s a country fan to do? Don’t be a “hayseed.” Get on over to Peter’s Pub for country music night with DJ JB. Check out their great specials: $5.50 fish bowls, $7.50 Smirnoff fish bowls, $2 Yuengling bottles (10 p.m. – midnight), and $5.50 Bud Lt. pitchers (7 p.m. to close). If you want to add some protein to the picture, try the $5 sandwiches ( 5 – 10 p.m.). Plus, unlike the summer country concerts, they’ll clean up and bag your trash. 116 Oakland Ave., Oakland.
