Hornsby's own music evolved significantly during this time period. Critics have suggested that the Dead's vibrant tradition of melding folk music and the blues with psychedelic rock in "loose-knit expressions" and extended jamming "further pushed outside the confines of mainstream pop". Critics have also commented upon the "close musical connection" formed between Hornsby and Jerry Garcia, suggesting that Hornsby's particular style of jazz-fueled improvisation added to the band's repertoire, and helped to revitalize and refocus Jerry Garcia's guitar solos in the band's sound. Hornsby's friendship with Garcia continued, both inside and outside the band, as the two "challenged" each other to expand their musicianship through several other album and live collaborations. Above all, Hornsby's musical versatility and ability to slip in and out of extended freeform jams won over longtime Grateful Dead fans.
