On previous "solo" albums, Carlos Santana had made noticeable stylistic changes and worked with jazz, pop, and even country musicians. On this, his fourth Carlos Santana release, the line between a "solo" and a "group" project is blurred; this record is really a catchall of Santana band outtakes and stray tracks. For example, included are an instrumental version of "Deeper, Dig Deeper" from Freedom, and an alternate take of "Hannibal" from Zebop!, as well as "Now That You Know" from the group's 1985 tour. Given the variety of material, the album is somewhat less focused than most Santana band albums, but there are individual tracks that are impressive, notably "trane," which features Tony Williams on drums. (Blues for Salvador won the Grammy Award for Best Rock Instrumental Performance).
