The not-so secluded stoner subculture of south London rap officially has new heroes in Lost World. Members Tee Stone and Skulls Pro joined forces recently to drop a joint EP, Space Mountain. The six-tracker is a slight shift from the sound usually associated with the pair, as they go all high energy and bring through their trap-leaning cloud rap. "Bud Free" is the set's centrepiece, and it's a carefree hazy rap anthem with hazy, hypnotic visuals to match. Listen and watch, after the jump.
