HIP-HOP
It's a little redundant for Minneapolis hip-hop star Dessa to get onstage to promote her new album, "Castor, the Twin," since that's exactly where it came from. She made the new recordings of mostly older tunes right after coming off the road with her ace band, which spiked the songs with jazzy inflections and arguably greater drama. It's not actually a live album, but it very much feels like it. In addition to her already notable bandmates such as Aby Wolf and Heiruspecs' Sean McPherson, she will be joined by Channy Casselle and Cecil Otter. Should be far from redundant.

According to its website, the Smokers Club was "sprouted in the summer of 2010 by a group of friends seeking to merge both their love of music and medicinal medicine." For its second-ever tour, the loose collective is trotting out Wu-Tang legend Method Man, buzzy Southerner Big K.R.I.T. and prolific/talented weed rapper Curren$y for a 35-city run. Don't think the MCs' emphasis on THC hog-ties their craft -- these are some capable and artful technicians. (9 p.m. Fri., First Avenue, 18 & older, $27.) Jay Boller
Like his friend and frequent collaborator Slug, Murs has become something of an underground hip-hop elder statesman. He came up in the late '90s, finding critical success as an indie rapper before taking his smart, plainspoken rhymes to a major label on 2008's "Murs for President," which netted mixed reviews. Independent once more, the Los Angeles-based MC released his fourth solo effort, "Love & Rockets, Vol. 1: The Transformation," last month. Opening are D.C.-based rapper Tabi Bonney, Jay-Z's producer pal Ski Beatz and others. (9 p.m. Tue., Fine Line, 18 & older, $15.) Boller
POP/ROCK
Although it can be difficult to tell the difference, They Might Be Giants continue to craft "adult" records alongside their popular kids albums. The latest is "Join Us," a playful but non-cutesy collection that shows the two Johns who front the band are still pretty serious about making clever, polka-spiked pop/rock. They're meeting their wide-aged fan base halfway this time: It's a 14-and-up show. Gold Motel opens. (7:30 p.m. Sat., First Avenue. $23.) Riemenschneider
It seems like only yesterday that bands like Hatebreed and Killswitch Engage were merging the crunchy breakdowns of '90s hardcore with heavy-metal riffage, the latter sprinkling in some melody for good measure. Not much has changed since metalcore's inception, but few have perfected the formula better than regional headbangers After the Burial (Minneapolis), Veil of Maya (Chicago) and Misery Signals (Milwaukee). (6 p.m. Sun., First Avenue, all ages, $15.50-$18.) Michael Rietmulder
The promotion company behind this tour is co-owned by a member of unlikely Top 40 stars Mumford & Sons, so it's not surprising that headliners Matthew & the Atlas -- with croaky, Springsteen-ish frontman Matt Hegarty -- trade in the same triumphant, Americana-by-numbers racket as the Mumfords. Ohio native David Mayfield, brother of alt-country starlet Jessica Lea Mayfield, provides a believable/bearded take on Neil Young at his most country. (9:30 p.m. Sun., 7th Street Entry, 18 & older, $12-$15.) Boller
