In 1968 the 2nd generation of BS&T went to work on the album that became the band's best-selling album. It was a mixture of pop, jazz, folk, and R&B. James Willian Guercio was brought in to produce the album because of his work with the Buckinghams and their horn arrangements.
The 2nd BS&T album was called simply "Blood Sweat and Tears." It had many top 40 hits that are sill propelling the band today.
