The tracks on Landmass were recorded on May 20, 2007,[5] live on the Star's End radio program in Philadelphia, Pennsylvania. Only a few hours after Steve Roach had given a concert at the Episcopal Church at Penn, his equipment was moved to the WXPN studio where, beginning a little after two in the morning, Roach performed and created each track. The sounds, themes, and sonic "sub-structures" were prepared ahead of time, and the tracks were later edited for length prior to their release.[6]
