Helium was an American alternative rock band formed during the summer of 1992. Under the original moniker of "Chupa," the band's founding members were Mary Lou Lord; Jason Hatfield, Juliana Hatfield's brother; Shawn King Devlin; and Brian Dunton. Devlin and Dunton were both also in the band Dumptruck before founding Helium.
Mary Timony, formerly of the band Autoclave, replaced Mary Lou Lord on vocals and guitar shortly after formation, as Lord was reluctant to use electric instrumentation. Following Hatfield's departure, the remaining members changed the band's name to Helium.
