Pulse Ultra was initially formed as Head Space in 1997[1] by guitarist Dominic Cifarelli and bassist Jeff Feldman.

Taproot guitarist Mike DeWolf, through their management team Velvet Hammer, later got the band signed with Atlantic Records.

In a post on the band's official forum, Zo stated that the split was amicable and they were all on good terms.

Jeff Feldman is now playing bass in electronic/avant-garde band Elsiane and is working on other numerous endeavours which include soundtrack music and a project titled Hallway Memoirs.

Maxx Zinno later played drums for the Los Angeles-based indie rock trio Run.
