The Free double B-side albums, 'Death Game'n' and 'rebuilt'x' are some interesting oddities; 'Death Game'n' is an archive of the very first songs together, reflecting the ebm/industrial and early videogame influence of their origins (esp. Zelda and Super Mario dungeon themes), while 'rebuilt'x' is a remix album of songs from that same time period, constructed over an 11-year timespan (so the first couple tracks are from late '97 and the last 2 are the newest tracks from '08).
The album covers are also a throwback, with 'rebuilt'x' being an obvious recreation of the 'Lunatic Harness' album by Mu-ziq (one of the most important catalyst albums for aphasein during 1997). The reel-to-reel has appropriately enough been replaced with the Amiga600. 'Death Game'n' on the other hand, is a nod to all the blank CD labels that were filled in on mix/demo CDs throughout the years (and mildly to Tortoise's 'TNT' album). The 'x and 'n from the titles reflect the transition from the early days of aphasia - aphasiax - aphasian to aphasein, and are also an homage to Squarepusher's 'Burningn'n Tree' early archive album. Plus, the titles fit the themes better. Enjoy the origin story.
