Zevious and Seabrook Power Plant were a perfect pair at Baltimore's Orion Sound Studios on Saturday night, each bringing a viciously complex brand of mathy rock to the table. Zevious' compositions stood out, building enormous tension and proving to be much more than just an exercise in counting out weird rhythms. Seabrook Power Plant was like a mix of extreme metal and prog, except with a banjo as lead instrument. It was about as ridiculous and amazing as that description would seem to imply.

Kevin Hufnagel led off with a contemplative solo acoustic guitar set:

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.

The experimental music fan has two very different but equally appealing avant-garde music options this weekend.

On Saturday, hop over to Twins Jazz for a free-jazz concert the likes of which the District doesn't get enough these days, as pianist Joel Futterman and reedist Ike Levin duo it up. Futterman played Twins Jazz a couple years ago with legendary New Orleans saxophonist Kidd Jordan, and immediately won me over with a style that is most easily compared to a somewhat more accessible Cecil Taylor. He's been playing with Levin at least since 2002, and this should be an excellent night for those who miss the shows like this that Transparent Productions used to put on regularly.

On Sunday, a trek up to Orion Sound Studios will be rewarded with a show by the always unpredictable Cheer-Accident, who last played there in April following their performance at Avant Fairfax, pictured above. This long-running Chicago band writes music by throwing genres and expectations into a blender and adding a dash of Zappa-like whimsy—and they come out with something completely different every time they do it. Baltimore bands Armed Elephant and Isthmus open; the latter's Isis/Neurosis brand of metal is great, if an odd fit for the bill.

Fresh off a well-reviewed performance at NEARfest, the most prestigious progressive rock festival in the United States (don't laugh), Mexican instrumental trio Cabezas de Cera are playing two dates this week in D.C. plus one in Baltimore. Cabezas de Cera aren't your typical bombastic prog band; rather, they combine folk, prog, free improv and a touch of the avant-garde into a fascinating and fairly uncategorizable mish-mash, and they've been doing it for about ten years now. While the basic format of the trio (plus a member credited as a "sound designer") is guitars/saxes/drums, in reality they play a bewildering array of instruments, from traditional instruments to nontraditional rock instruments like the Chapman Stick, plus a variety of homemade implements.

Cabezas de Cera are playing the Kennedy Center's Millennium Stage tonight at 6pm sharp, then at Artomatic tomorrow night at 8:30pm. Both these shows are free. On Sunday, they will make an appearance at Orion Sound Studios in Baltimore alongside Might Could – you can expect a longer set at this show for your $15. Orion is at 2903 Whittington Ave, shows are usually scheduled to start around 8pm.

Apparently I picked the worst time possible to take a long weekend and skip town, because for the experimental jazz/rock fan there is something awesome happening every night for the next four nights. Check it out:

• Thursday, April 16: Composer/arranger Ed Palermo will be conducting the U.S. Army Blues ensemble in a program comprised entirely of the music of Frank Zappa. (What.) This takes place at 7:30pm in Brueker Hall at Fort Myer – 400 McNair Road, Fort Myer, VA.
• Friday, April 17: Cuneiform Records artist Beat Circus (Myspace), a rock ensemble whose current lineup includes all kinds of strings and horns (including a tuba), will be at Orion Sound Studios south of Baltimore. Opening is Fern Knight, with whom I'm not familiar but who are described as a mix of "Krautrock, UK folk, and early baroque and renaissance music." Cool. Orion is at 2903 Whittington Ave., Baltimore, MD. Show at 8pm.
• Saturday, April 18: The Tiptons Saxophone Quartet (Myspace), plus drummer, performing at Orion. This sax quartet has a diverse, fun repertoire that "ranges from New Orleans 'second-line' to jazz, Afro-Cuban to Balkan, klezmer and beyond." Show at 8pm.
• Sunday, April 19: Japan's psychedelic rockers Acid Mothers Temple (Myspace) hit DC9. AMT seems to be constantly on tour, and their shows are semi-legendary for their stoned-out, hazy heaviness. Also, Japanese psych-rock is pretty much just reliably crazy. Show is at 9pm, Sonic Suicide Squad are opening.
