Spirit in Concert depicts a 40-minute concert performance by one of the latter-day lineups of Spirit at an unknown outdoor location during daylight hours. Presumably, the band was part of some small music festival (there appear to be a couple of thousand people in the audience), perhaps warming up for some other performer. Randy California is front and center, playing guitar and singing, and behind him is drummer Ed Cassidy, who gets an extended solo during "Nothin' to Hide." They are joined by a bass player and keyboard player (probably Scott Monahan). The band plays some of Spirit's best-known songs, "I Got a Line on You," "Nature's Way," "1984," "Nothin' to Hide," and "Animal Zoo," plus a couple of songs never released on record, "Island of Roses" and "Sweet Child." Both of them are typical catchy rock songs in the familiar Spirit mold. California is a good frontman, and the crowd is enthusiastic, especially when he runs through the audience still playing guitar during "If I Miss the Train." The sound quality is adequate, but no more, and on the whole this is not a high-quality release. Rather, it captures one of what were no doubt thousands of Spirit performances over the years.
