Wilco play at Wolftrap on Wednesday night with Conor Oberst and the Mystic Valley Band.

MONDAY
>> Those revered veterans of indie rock, Sonic Youth, begin their two-night stand at the 9:30 Club tonight. They’re on the road in support of their sixteenth studio album, The Eternal, just released on Matador last month. And while the Yoof may be the elder statesmen on the scene these days and that once-raw noise seems just a tad more sterile, their late-period catalog has shown remarkable consistency, guaranteeing at least one or two gems per release. ‘Course, their 9:30 shows have been sold out for a good while now. Maybe some luck here? Doors 7 p.m., with openers Endless Boogie.

>> From Raleigh, NC come Bowerbirds — no strangers to the District — a delightfully quirky folk group to the Black Cat Mainstage Backstage. Their Hymns for a Dark Horse garnered very strong reviews when it came out two years back, and their newest one, Upper Air, actually sees release tomorrow — a perfect opportunity to get a sneak preview of the disc, both live and on record. Mark Charles Heidinger — aka Vandaveer — joins them, and will hopefully be previewing some tunes from his upcoming LP, Divide and Conquer, out in August. Megafaun will be performing as well. Doors at 8 p.m., $12.

>> The weather’s beautiful, and over at Fort Reno they’ll be serving up Go Home Robot, Seamonsters, and Power Pirate. Free, 7:15 p.m.

>> Something of a quiet week around here, but Monday’s actually kinda loaded. If you routinely take your roots tunes a little looser and more off the cuff than what the Black Cat has on offer (see above), then The Federal Reserve Collective hits the Iota Club and Cafe in Arlington with its First Mondays series. $5, Doors at 8 p.m.
