Ultra-Obscene is the debut studio album by Breakbeat Era, a collaborative project consisting of Roni Size, DJ Die, and Leonie Laws.

It peaked at number 31 on the UK Albums Chart.

[2] 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.

"[3] Laurence Phelan of The Independent called it "the first successful vocal d'n'b album.

"[7] All tracks are written by Roni Size, DJ Die, and Leonie LawsCredits adapted from liner notes.
