Matrices 7E-1117-A SP / 7E-1117-B SP; SP identifies Specialty. Multiple 1977 US matrix and plant variants exist, including PRC and other Specialty cuts, so this is an original 1977 pressing rather than an established first.
Specialty, in Olyphant, Pennsylvania, is the first East Coast plant identified in the collection; most others so far are West Coast. Also the closest thing on the rock shelf to the jazz side: horns, upright bass, and the record where Waits started writing for that instrumentation.
