GET A MASTER CLASS IN HOUSE MUSIC FROM DERRICK CARTER

Some general rules: Every techno aficionado should witness Derrick May, Juan Atkins, or Kevin Saunderson in the flesh at least once in his or her life, if given the chance. Similarly, every house head should catch at least one live appearance by veteran Chicago DJ Derrick Carter. If you want to experience a master at work, you owe it to yourself to check out Carter's uproarious and diverse sets—disco, soul, jazz, and synth-pop cuts commonly worm their way into his sets, along with all the crucial house jams you'd expect from this sage selector—mixed with acute technical skills and a keen sense for maximizing feel-good vibes. Carter is also possibly the only person ever to remix tracks by both the Human League and Tortoise. Seattle needs to make amends for the poor Valentine's Day turnout for fellow Chicago house legend DJ Pierre. Q, 8 pm, $10 till 11 pm/$15 after, 21+.

XXYYXX, Giraffage, Kid Smpl

Orlando, Florida, producer XXYYXX (aka Marcel Everett) is already a highly in-demand remixer at age 17 (if his Facebook page is to be believed). The kid's already got the chilled, tinkly, subtly emotional style of electronic-music production down to an artful science; he cheekily dubs it "fro-fi," which is a brilliant coinage. Combining oddly angled funk and shoegaze-rock atmospheres, XXYYXX creates music that's ideally geared for those who like to wind down and nod their heads in style. He also has a spazzy IDM-ish track titled "Don't Take This Song Seriously."Canadian producer Teen Daze had to drop off this bill for bureaucratic reasons (apparently his squeaky-clean electronic music represents a threat to US security), so San Francisco's Giraffage will replace him. This Giraffage guy (aka Charlie Yin) is yet another accomplished modernizer of R&B, throwing wonky rhythmic changeups into the genre's usual ultraslick structures. He applies plenty of vocal time-stretching and other normality-warping tricks to his heavy-lidded yet buoyant take on rizzim and blooz, and I'm feelin' it. Check out the new Needs album on the renowned Alpha Pup label for easy mood elevation. Re-bar, 10 pm, $13, 21+.

PDX ACID-HOUSE RENOVATORS ETBONZ AND ACID FARM

Etbonz—Portland producer Elliott Thomas—creates soulful, questing, minimal house that's occasionally powered by Roland 303 acid twangularity. Fellow PDXers Acid Farm, as you may surmise from the handle, purvey a similar throwback sound. The duo—Morgan Hynson and Jesse Mejia—have a track called "Hard Drugs (Acid)," in case there were any doubts about their intentions. If a rave is ever going to happen in the tiny Cairo, these are the folks to instigate it. With Temples and USF. Cairo, 8 pm, $5, all ages.
