Source Crossfire is a searing, brooding collection that documents the recorded output of Sofa one of Montreal's most shadowy, notorious, captivating underground art-rock ensembles of the mid-90s, and the first band to be released on Constellation charting the quartet’s febrile evolution through sonic palettes of North American post-hardcore and slowcore admixed with early UK post-punk, goth and dark lounge. In the words of one music writer of the era: "Like Slint and Big Black meeting for a Joy Division reunion."

Source Crossfire rounds up Sofa’s 1997 album Grey (the only full-length from Constellation’s early years yet to be given vinyl reissue treatment) along with selections from the band’s two prior self-released cassettes. What began as a straightforward Grey vinyl re-issue project soon evolved into an opportunity for something just a little more considered than “album plus-bonus-tracks”. Record #1 reimagines Grey with vinyl in mind, newly sequenced to create distinct loud/fast and soft/slow sides. Record #2 mirrors this, with four tracks of louder (and mostly faster) pitch-black material on Side One and three signature examples of the band's sombre early balladry on Side Two all culled from the Town Unsafe and Record cassette material from 1995.
