The little club that could — O’Leaver’s — is hosting two of the best shows of the weekend. It starts tonight with Brimstone Howl (You read about them here yesterday) celebrating the release of their new CD on Alive Records, Big Deal, What’s He Done Lately? Opening is Lover!, a Memphis/Chicago band that records on underground label HoZac Records (here’s Lover’s Myspace page). If that weren’t enough, also opening is John Barrett’s Bass Drum of Death, a duo that has a 7-inch out on Fat Possum (Here’s their Myspace page). All three for a mere $5. Show starts at 9:30.

Also tonight, Canadian sludge-space band Pink Mountaintops returns to Omaha, this time at Slowdown Jr. with Dim Light and The Mulanix Street Orchestra. $10, 9 p.m. And I would be remiss in not mentioning the Big Al video shoot tonight at Barley St. Tavern. Opening is Jes Winter and Sarah Benck. $5, 9 p.m. While over at The Waiting Room Detroit dance-rock band Electric Six plays with The Gay Blades & Millions of Brazilians. $13, 9 p.m.

Saturday night, it’s back to O’Leaver’s for the Omaha debut of the reunited Mercy Rule — the lights, the sounds, the songs, it’ll be 1994 all over again. Opening is Speed! Nebraska bands The Wagon Blasters (ex-Frontier Trust) and Ideal Cleaners, along with Jake Joyce McCoy. $5, 9:30 p.m.

Also Saturday, Vancouver rockers Japandroids (Polyvinyl Records) plays at Slowdown Jr. with West Palm Beach masters of echo rock Surfer Blood (Kanine Records) and The Answer Team. $10, 9 p.m.

The annual Homeless for the Holidays benefit concert also is going on Saturday night at The Hideout (320. So. 72nd St.). $10, 7:30 p.m.
