Ultra-Obscene

Ultra-Obscene is the debut studio album by Breakbeat Era, a collaborative project consisting of Roni Size, DJ Die, and Leonie Laws. It was released on XL Recordings in 1999. It peaked at number 31 on the UK Albums Chart.

Critical reception
Rick Anderson of AllMusic says, "Leonie Laws is not a tuneless singer, by any means, but her approach is more punk than pop, and the instrumental accompaniment is straight out of the 'darkcore' subgenre of drum'n'bass, a style typified by minor chords and creepy, robotic basslines." Laurence Phelan of The Independent called it "the first successful vocal d'n'b album."
