American garage rock band The Electric Prunes released their second studio album Underground in 1967. The band wrote many of the songs for this psychedelic garage rock album, which would be the last one featuring the original band members. The guitar interplay between Jim Lowe, Ken Williams and James "Weasel" Spagnola is as strong as on their first album. It extends the variety of psych-pop heard on their debut, while honing a tighter and heavier sound. In 2011, it was included in NME's "The 100 Greatest Albums You've Never Heard" list. We can't argue on that as this is definitely one of the better acid/punk/psych albums from the 60's.
