Thrill Jockey instrumental duo Rome are, like many of the acts on the Chicago-based independent label, generally grouped in as loose adherents of "post-rock," a period-genre arising in the mid-'90s to refer to rock-based bands utilizing the instruments and structures of the music in a non-traditionalist or otherwise heavily mutated fashion. Unlike other Thrill Jocky artists such as Tortoise and Trans-Am, however, Rome draw less obviously from the past, using instruments closely associated with dub (melodica, studio effects), ambient (synthesizers, found sounds), industrial (machine beats, abrasive sounds), and space music (soundtrack-y atmospherics), but fashioning from them a sound which lay clearly beyond the boundaries of each.
