Just because the scheduled Linkin Park and Prodigy show at the American Airlines Center has been postponed until Wednesday, March 2, doesn't mean you can't catch another musical act this evening.

As a matter of fact, we have a plethora of worthy options for the discerning music fan.

The Will Callers at Lola's Saloon in Fort Worth
Perseverance is a word sometimes bandied about without a lot of discretion, but in the case of Fort Worth's The Will Callers, it's a factual application. Some might already know the story of how two members of the band were tragically killed in an auto accident right as The Will Callers were in the throes of a contest for a free record deal. It was a tragic turn of events, but the remaining two members quickly regrouped, won the contest and have now come back for an unlikely encore. And guess what? Jake Murphy and crew are damn good to boot. Alt-country doesn't get much better than this, and rarely does a band really deserve your attention. But these guys do.

NoBunny, Video, Cats in Heat and Idiot at Rubber Gloves Rehearsal Studio in Denton
This is the kind of quadruple-bill that makes an indie music fan smile. Oakland's NoBunny is the mastermind of Justin Champlin, a rather warped dude who has some weird ideas but great punk rock instincts. His is one of those bands that you just have to experience live to truly appreciate. Meanwhile, adding to the animal motif of tonight's bill is Denton's own Cats in Heat, a band with a great name who are a relatively new entry onto the scene.

Rehab, Smooth Choppy, Secret of Boris and Twice Broken at Trees
Rehab's Danny Boone started this band after several stints in -- you guessed it -- rehab. Seems drug and alcohol addiction are a big part of Boone's history. The first version of Rehab lasted from 1998 to 2002, and then the Southern rock/hip-hop band predictably fell apart. But Boone created a new (and slightly improved) Rehab in 2005, and this quintet seems to be holding itself together. Not nearly as obnoxious as one might think, Boone is actually a fairly astute singer-songwriter who comes across as a nerdy version of Kid Rock. Not sure that's much of a recommendation, but it's a start.

Dallas Observer's First Ever Tweet-Up Party at Big Al's McKinney Avenue Tavern
There will be some live music at this thing, apparently. But, mostly, it's about checking out and seeing if people are as attractive as their avatars on Twitter make them out to be. Which is almost never the case, but, oh well. Maybe tonight will prove different.
