The record includes "Sky Pilot", an anti-war song of the Vietnam War era, and "Monterey", the band's tribute to the 1967 Monterey Pop Festival. Reviewer Bruce Eder of AllMusic describes the song "All Is One" as "unique in the history of pop music as a psychedelic piece, mixing bagpipes, sitar, oboes, horns, flutes, and a fairly idiotic lyric, all within the framework of a piece that picks up its tempo like the dance music from Zorba the Greek while mimicking the Spencer Davis Group's "Gimme Some Lovin'".
The Twain Shall Meet peaked at No. 79 on the U.S. Billboard Top LPs during a twenty nine-week stay on the chart.[2]
