This L.A. art-pop outfit only lasted for two albums, but they left a radiant, colorful splatter on an early-'90s alt-rock landscape dominated by grim grunge. Their 1990 debut, Bellybutton, channeled the innocence of early Beatles through jaunty sing-alongs like “Baby's Coming Back,” but on their 1993 follow-up, Spilt Milk, their sound turned more powerful and fantastical. With “The Ghost at Number One,” Jellyfish forged the missing link between Queen and Weezer, displaying the sort of elaborate arrangements that have since made multi-instrumentalists Jason Falkner and Roger Manning in-demand players for the likes of Beck and Air.
