I.M.P. has announced two more shows at the Lincoln Theatre, and the only thing they have in common is a certain illegal substance: Fiona Apple plays the theater with Blake Mills Oct. 25 and Oct. 26, and Cheech & Chong perform there Oct. 24.

The 9:30 Club and Merriweather Post Pavilion promoter recently took over the historic African-American theater on U Street NW and announced a glaringly white lineup including Laura Marling, Travis, KT Tunstall, Matt Nathanson, and Neko Case.

Tickets for Fiona Apple and Cheech & Chong go on sale Friday at 10 a.m. on Ticketfly.
