The piece runs fluently through all 29 minutes, and all four songs are linked through consistent bouts of chaos and lyrics glued by the metaphor of using mosquitoes as a symbol for mankind, society, and population control.

The reissue of this EP features cover art depicting control towers (the central theme of Celestial).

Although it represents Isis' first studio release, it is actually their third recording as a group after two demo productions.

The EP was the last recording containing founding member Chris Mereschuk, and Randy Larson left the band shortly before its recording;[3] as such, “[t]here are things on this record that certainly would not have [sic] been written were it not for those people, and it represented a set of voices that was no longer apparent in the subsequent recordings.”[3] Sonically, Aaron Turner feels that Isis “were starting to find [their] voice” with the release, citing “Life Under the Swatter” as “the beginning of a path on which we would synthesize heavy riffing with complex rhythmic patterns and textural/subdued passages”.

[4] "Relocation Swarm" features dialogue sampled from the season two finale of Twin Peaks.
