CHEAP BOOKS--If you're like me, a nerdy bookworm who's never even seen an episode of Alias--you spend about 80 million dollars a year on books. But if you go to this sale, you might have a shot at reducing it to 40 million. Once a year, Powell's cleans out their shelves and sells all their old books at Pioneer Place. Not a lot of new stuff, but still some good stuff. KD

Pioneer Courthouse Square, Thursday the 18th, Friday the 19th, and Saturday the 20th, 9am-9pm, free

MUSIC--Under jurisdiction of KRS-One, May 13-19 is Hiphop Appreciation Week; do you know your elders? Let DJ Cheesy Mack school you on his beatific ride through the beginnings of hiphop and house. JS

Madame Butterfly, 425 SW Stark, 525-0033, 10 pm


MUSIC--When's the last time your boss released a record featuring the talents of his/her employees? Stumptown Coffee celebrates the release of their compilation tonight, titled, appropriately enough, Worker's Comp. A good name for a sincerely great album, and tonight' s show features employees Nicholas Marshall (Igloo), Schicky Gnarowitz, and the booty-riffic Booty Proof. WSH

Blackbird, 3728 NE Sandy, 282-9949, 9 pm, $5

ANIMATION--Get your play-group together and go wacky with the latest brainchild of local kook Beau Von Hinklywinkle. It's an animation festival featuring the recent work of Dot & Line, Tom of Finland, Helen Hill, Tim Burton, and many more... MS

Disjecta, 116 NE Russell, 335-6979, 9 pm, $2


MUSIC--With four turntables and easy fingers, Ming & FS glom hiphop and drum 'n' bass together into eruptions of teeth-sinking rhythm and cosmic dance-tastical bootythumps. Phantasmagorical beat-raunching straight outta Hell's Kitchen. JS

Tonic, 3100 NE Sandy, 238-0543, 10 pm, $8-10

METAL--My favorite Cannibal Corpse song title is "Compelled to Lacerate," because it epitomizes the band. Not only are they compelled to shred your eardrums, but they just have to go completely over the top. Their dark, fast metal hardcore gives 150 percent, 175 percent of the time. This will be a black t-shirt sweat-a-thon. Bring a towel. KS

w/ Dark Funeral, Pissing Razors, Incantation; B-Complex, 315 SE 2nd, 224-TIXX, 9 pm, $17

Dude! It's 4:20!--Q: What peels a chronic-ified ass off the couch faster than takeout? A: Live hiphop. Catch The Session's MC Battle and puff tuff with the likes of Blak Scienz Tribe, Madgesdiq, Evil E, and Sound Sculptures. MS

Rusty Nail (Lewis & Clark), 0615 SW Talatine Hill Rd., 768-7000 x 8495, 7 pm, $4-6


Nick Cave--In my opinion, the dark and glamorous Nick Cave can never get old or overplayed. I don' t care what you say. I like the way people with laryngitis sound when they sing, okay? KD

Crystal Ballroom, 1332 W Burnside, 224-4400, 9 pm, $30

DANCE--Tender, fierce, sprawling, claustrophobic. A dozen new choreographed dance narratives (and fully fledged non-narrative aesthetic pieces) from the elegant mind of Mary Oslund. Scored in part by the godly vibrant sounds of Courtney Von Drehle from Three Leg Torso. PB

Conduit, 918 SW Yamhill, 4th Floor, 221-5857, x. 3, 8:30 pm, $13


RAP POP--Though the headliner for this show is Ja Rule, for my money the top draw is still Ludacris. His odes to the dirty south include "What's Your Fantasy," (I Got Hoes in Different) "Area Codes," and my current favorite radio hit: "Welcome to Atlanta where the playas play/And we ride on them things like every day/Big beats, hit streets, see gangsta's roamin'/And parties don't stop til' eight in the mornin.'" Damn right. WSH

Memorial Coliseum, 224-4400, 7 pm, $20 general admission


FILM--Anyone who's anyone knows that hiphop is "in" right now. So, if you don't want to sound like a big idiot when you're discussing the latest cuts and rhymes with your "homies," go see Scratch--a documentary about nightclub DJing featuring Grand Wizard Theodore, Grandmixer DXT, and DJ Qbert, with a, uh... "phat" soundtrack. KS

Cinema 21, 616 NW 21st, 223-4515, 7 & 9 pm, $6

BENEFIT SHOW--Community Alliance of Tenants is fighting the good fight--keeping gentrification at bay, honest landlords, and rents low. What's more, they are throwing us a party! That's right, instead of cramming do-goodin' rhetoric down our collective throats, they are feeding and entertaining us. A smorgasbord will be presented by the cooks from Colosso, Caswell, and Gino's, accompanied by acoustic music from Sean Croghan and Karaoke from Hell. PB

Berbati's, 231 SW Ankeny, food at 5:30 pm, music at 7 pm; $25 for dinner; $10 for music only


MUSIC--It's hard enough to play one freaking instrument... but three or four? That's right, it's "One Man Band," night at the Satyricon with the Mississippi blues stylings of Bob Log III, the corndog slide guitar of Frank Furter & The Hot Dogs, and the footstompin' rock of King Louie One Man Band, featuring the tune "Don't You Cook That Cabbage (It Makes the Whole House Stink)." Great God-all-mighty! Who needs more than one? WSH

Satyricon, 125 NW 6th, 243-2380, 9:30, $8 advance
