>>Flex Mathews’ Goodwill Ink brings together some of the area’s best for this mid-week hip-hop affair at the Velvet Lounge. Slated to participate are Oddisee, W. Ellington Felton, and Roddy Rod, among others. 8 p.m., $7.

THURSDAY:
>>It’s been over a decade since DJ Shadow (pictured to the right) released the groundbreaking Endtroducing… album, which almost single-handedly elevated sampling to an art form. Cut Chemist (pictured to the left) made his name as a member of Jurassic 5 and as a producer who loves to go back to sounds from hip-hop’s good ole days. Together, they make for a potent turntablist billing for their “Hard Sell” show at the 9:30 Club, along with opening act Kid Koala. 7:30 p.m., $35.

FRIDAY:
>>The previously displaced “Beat Grinder” series makes its return with a championship round. Four local producers will be putting forth their best efforts to capture the crown. Included in the competition are Slimkat 78, The Unknown, Nick Da 1da, and Infinite. Hosting duties will be up to Enoch while Underdog, Damu, and Earth 1ne will handle the turntables. The event will kick off at 7 p.m. at the Universal Capoeira Angola Center (rear of the old Republic Gardens), 1351 U Street NW. $3.

>>The recurring Deep Sang event at the Rock And Roll Hotel promises lesser-known disco (a.k.a. the good stuff), boogie, funk, and other danceable tunes from a bygone era. 9:30 p.m., Free.

MONDAY:
>>Signed to the rekindled Memphis soul powerhouse label, Stax Records, Angie Stone is mounting a comeback of her own. Last fall she released The Art of Love & War which capitalized on her throwback rich vocals and reworkings of classic tunes by the likes of Curtis Mayfield. She’ll be appearing at the Birchmere. 7:30 p.m., $59.50.
