a club that would admit them, when they heard banjo music. They followed the music to its source, Dana Morgan's Music Store. They encountered a 21-year-old Jerry Garcia, oblivious to the date, waiting for his students to arrive. Weir and Garcia spent the night playing music together and then decided to form a band. The Beatles significantly influenced their musical direction. "The Beatles were why we turned from a jug band into a rock 'n' roll band," said Bob Weir. "What we saw them doing was impossibly attractive. I couldn't think of anything else more worth doing." Originally called Mother McCree's Uptown Jug Champions, the band was later renamed The Warlocks and eventually the Grateful Dead.
Weir played rhythm guitar and sang a large portion of the lead vocals through all of the Dead's 30-year career. In the fall of 1968, the Dead played some concerts without Weir and Ron "Pigpen" McKernan. These shows, with the band billed as "Mickey and the Hartbeats", were intermixed with full-lineup Grateful Dead concerts. In his biography of Jerry Garcia, Blair Jackson notes, "Garcia and Lesh determined that Weir and Pigpen were not pulling their weight musically in the band... Most of the band fights at this time were about Bobby's guitar playing." Late in the year, the band relented and took Weir and Pigpen back in full-time.
The incident apparently led to a period of significant growth in Weir's guitar playing. Phil Lesh said that when drummer Mickey Hart left the band temporarily in early 1971, he was able to hear Weir's playing more clearly than ever and "I found myself astonished, delighted and excited beyond measure at what Bobby was doing." Lesh described Weir's playing as "quirky, whimsical and goofy" and noted his ability to play chord voicings on the guitar (with only four fingers) that one would normally hear from a keyboard (with up to ten fingers).
In the late 1970s, Weir began to experiment with slide guitar techniques and perform certain songs during Dead shows using the slide. His unique guitar style is strongly influenced by the hard bop pianist McCoy Tyner and he has cited artists as diverse as John Coltrane, the Rev. Gary Davis, and Igor Stravinsky as influences.
