Deep Space: Lefto

Dance-music deity François K and his Deep Space soiree—focusing on dub in all its glorious, echo-drenched forms, but extending its reach to all types of underground dance music—have been ruling Monday night for years. Tonight's party features a guest set from Belgium's Lefto, a brilliant funk, hip-hop, soul and jazz maven affiliated with such labels as Brownswood, Blue Note and Stones Throw.
