In honor of their 30th anniversary this year, 4AD and Beggar's Archive will release a four-disc box set compiling the work of British electronic music pioneers Colourbox.

Formed by brothers Steven and Martyn Young (the latter of whom compiled this set), Colourbox stood apart, sonically, from fellow labelmates This Mortal Coil and Dead Can Dance, relying on a wide palette featuring reggae rhythms and sample-heavy riffs.

Not much has been heard from the group since their 1987 split, which happened at a most inconvenient time: their most successful commercial venture, a collaboration with dream-pop duo A.R. Kane under the moniker M|A|R|R|S (the supergroup's sole single, "Pump Up the Volume," topped the British charts and went to No. 13 in America).

The four-disc box includes everything the group commercially released - a 1983 EP and a 1985 LP (both self-titled), a bonus EP included with initial copies of the aforementioned album, and two discs of single sides - and is appended by an unreleased rough mix of album track "Arena" and a cadre of live tracks recorded for the BBC.

The whole set is available May 22 and can be ordered from 4AD and Amazon. Hit the jump to find the full track list.
