Bob Weir didn't start out as a frontman. Despite being a founding member of the Grateful Dead, it was Jerry Garcia who served as the band's tie-dyed pied piper and de facto leader of free-form jams. Serving for years as the middle man between Garcia's articulated lead guitar and Phil Lesh's avant-garde bass lines, Weir made significant strides in his own songwriting ability. When Garcia died, Weir and the rest of the band mounted their own respective musical endeavors to keep the strange trip of the Dead from fading away. With incessant touring bringing the spirit of psychedelica to a live audience (Weir's last studio album was released in 2000), Weir and his band, Ratdog, play at Innsbrook Pavilion with openers Moe on Wednesday, July 8, with gates opening at 5:30 p.m. $18-$35. 423-6589.
