Featuring remixes of earlier material, it focuses on heavy drums and bass guitar, with echoing vocals to underscore the intense percussive rhythm.

Carlton and Aston Barrett and Augustus Pablo contributed music, while vocal fragments include Hudson, Horace Andy and Big Youth.

[4][8] The Wire identified as among the album's strengths "[s]tuttering melodica, squelching keyboard and guitar chops and a mix which dropped instruments in and out of the sound picture every few bars".

[2] Hudson did not use the processed sound effects that later became common in the movement,[8] a lack cited as "refreshing" by Bradley, who noted that such early sets reflected "the remixer's art in its purest form".

[7] The album was recorded with Carlton and Aston Barrett of Bob Marley & The Wailers on drums and bass, with additional music supplied by melodica virtuoso Augustus Pablo.
