B, S & T; 4 (also expanded as Blood, Sweat & Tears; 4) is the fourth album by the band Blood, Sweat & Tears, released in June 1971. It peaked at number 10 on the Billboard Pop albums chart.
The band invited former member Al Kooper to contribute the song "John the Baptist (Holy John)". Trombonist Dave Bargeron replaced Jerry Hyman.
David Clayton-Thomas left as lead vocalist to pursue a solo career after the release of B, S & T; 4, as did founding members Dick Halligan and Fred Lipsius. Clayton-Thomas would return to the lineup for 1975's New City.
AllMusic critic William Ruhlman wrote that "the band's cohesion seemed to be disintegrating... Although the album scraped the Top Ten briefly and went gold, it marked the end of BS&T's period of wide commercial success on records."[1]
