4AD this spring will commemorate the 30th anniversary of genre-bending electronic pioneers Colourbox by collecting the group’s full studio output in a four-disc, 59-track box set that includes the free mini-album given away along with initial pressing of the group’s 1985 debut, plus 12-inch mixes and a BBC session.

The five-disc World Party box set announced last month will be released April 10 and comprised entirely of previously unreleased material: 70 never-before-heard tracks including new songs and an ‘unheard history of rare studio gems, live sessions, concert recordings, radio interviews, covers, demos and B-sides.’

The Pixies have yet to record a new album since reuniting in 2004, but frontman Black Francis has been no stranger to the recording studio in those intervening years, and, in April, will release ‘Let the People Speak,’ his second effort with wife Violet Clark as the indie/electropop duo Grand Duchy.

Karl Wallinger’s long-dormant World Party today announced plans for a forthcoming 5-disc box set called ‘Arkeology’ that will feature new songs, live recordings and cover versions, as well as ‘lots of pictures,’ liner notes and something called the ‘the amazing any-year diary.’

Last fall, Simple Minds announced plans to release a new box set containing the band’s first five albums and an untold number of bonus cuts — and now, with the collection and accompanying European tour due next month, we’re finally getting a look at the set’s tracklist, via our friends at The Second Disc.

Midnight Oil will be the subject of a career-spanning, multi-disc box set next year that guitarist Jim Moginie promises ‘is going to be amazing in its depth and presentation of the band’s career, with rare recordings and so far unseen and unheard film and music.’

Elvis Costello’s new live box set ‘The Return of the Spectacular Spinning Songbook!!!’ is currently listed at $262.39 on Amazon.com, and if you think that’s a ridiculous price for a release that features just one CD, one DVD and one 10-inch vinyl record’s worth of music, you’re not alone — Costello himself does, too.
