Tomorrow: Although the guitar trio Zevious started off as a jazz combo, it quickly spiced up its compositions with strong hints of math rock, complex prog, and even a touch of technical metal. The group recently released its latest album, After the Air Raid, on Cuneiform Records, a perfect fit if there ever was one. Zevious’ music, like many bands’ in this ultratechnical realm, can sound somewhat academic on record, but this kind of stuff is often jaw-droppingly intense and tight in concert.

The supporting bands on the bill are worthy of note, as well: Seabrook Power Plant is a punk-jazz trio featuring Brandon Seabrook, who in the words of show promoter Mike Potter is “a likely candidate for World’s Least Rustic Banjo Player.” Also on the bill is a solo acoustic guitar set from Kevin Hufnagel, best known as a member of tech-metal group Dysrhythmia and also a new member of the reformed legendary death metal group Gorguts.The show takes place at 8 p.m. at Orion Sound Studios, 2903 Whittington Ave., Baltimore. $10.

Sunday: We covered drummer Allison Miller‘s new ensemble, Boom Tic Boom, in Jazz Setlist yesterday. While Boom Tic Boom is on its surface a relatively straightforward jazz group, the individual members have gained notice playing in a number of fascinating avant-jazz projects. Hearing violinist Jenny Scheinman in this context—-she only plays on one track on Boom Tic Boom’s studio album—-will be particularly interesting, as Scheinman’s background ranges from her own solo folky/Americana all the way to esoteric stuff like free-jazz blowouts with Rova::Orkestrova and Eastern European tinged prog-rock with Charming Hostess. Bossa, 2463 18th St. NW, 8 p.m. $5.
