Originally released in advance of their 2003 album Summer Sun, this single collection contains 4 renditions of Sun Ra's percussive anthem "Nuclear War." The first version is by the basic Yo La Tengo trio. It is followed by a 16-minute jam featuring Daniel Carter, Sabir Mateen, Roy Campbell, Susie Ibarra and Josh Madell. The third version features 11 young children singing along, and the fourth version is a remix by Ozone hip hop experimentalist Mike Ladd.
