Tonight is one of the busiest music nights of the year, but before we get to that, a brief recap of last night’s show at O’Leaver’s. I tapped out four notes on my iPhone during Dim Light’s set: “whiskey swagger,” “swing/waltz,” “Mark Lanegan (Gutter Twins),” “peeling black paint on metal pipes.” “Whiskey swagger” was how someone sitting next to me at the bar (Brady) described Dim Light’s dirty, bluesy, just-rolled-out-of-bed-with-a-hangover rock. It’s tired and anxious but ultimately carefree (or care less). Their brutal sound has a natural swing, which swings even farther when married to a waltz-time rhythm (as it was on a few numbers). Frontman Cooper Moon’s stature and tone reminded me of Mark Lanegan singing dead-end rock songs that conjure visions of broken factories and industrial blight. With Boz Hicks on drums (Domestica) and Rhodes on bass, it all works with a gut-stabbing efficiency. I saw these guys at The Waiting Room in January and thought they sounded like sludge-core (but the headache I had that night might have had something to do with that). Last night, they were much more refined, and even (dare I say it) downright catchy. This is a band to watch out for.

Voodoo Organist, who has played at O’Leaver’s — what, 100 times? — was exactly what I expected: A guy playing an organ (and Theremin) handling vocals backed by a guy on drums. It was loung-y, kitschy, horror-billy rock. Good for what it was. Not something I’d seek out a second time, but judging by the crowd reaction, I’d say most of the 20 or so on hand would (and have).

There are a lot of shows going on tonight, most of them simultaneously. The early show is David Byrne at The Holland. Judging by the set list, this is the closest you’re going to get to hearing a Talking Heads concert until their next reunion (which may never happen). It is not sold out, and at that price point ($48-$78) probably won’t be. Starts at 8 sharp with no opening act, so get there on time.

The late shows are many. Two of them I mentioned yesterday — Ladyfinger at Slowdown with Mountain High and Techlepathy ($7, 9 p.m.), and Little Brazil at The Waiting Room with Crooked Fingers and Uglysuit ($10, 9 p.m.). You’ll find me downtown, as I just saw LB a month or so ago.

Also tonight, Tomato a Day is slated to play at The Saddle Creek Bar & Grill with Boy and It’s True. 9 p.m., no idea on the price.

At The Barley Street, Darren Keen plays along with Talkin’ Mountain, Physics of Meaning and Western Electric. $4, 9 p.m.

And finally, at PS Collective, Midwest Dilemma kicks off its fall tour that will take them to New York City and back, finishing up Nov. 2 in Des Moines. No idea who or how many will be tagging along in the van(s). Opening is Anniversaire, Tim Wildsmith and Kyle Harvey. $5, 10 p.m.

Saturday is dominated by the SLAM Omaha benefit show at The Waiting Room featuring the reunion of The Movies, as well as Sarah Benck & The Robbers, Bloodcow, Filter Kings, Icares, Ground Tyrants, Two Drag Club, Kill Bosby and Brad Hoshaw, all for a $10 donation. Show starts at 6:30.
