The 1979 EP was originally part of the Aeroplane Flies High box set, but if you're lucky enough to find it sold separately, go ahead and buy it. It has the classic "1979" plus five cuts that didn't make it onto Mellon Collie. "Ugly," an ode to low self-esteem, has kind of a Cars sound to it, and it's one of the Pumpkins' most interesting tracks. "The Boy" and "Believe" are two poppier numbers written by James Iha ("Believe" is my favorite of the two). The last song, "Set the Ray to Jerry," is one of my favorite Pumpkins songs.
This CD is fun to listen to. It showcases the Pumpkins' alternative pop side very well. If you see this in a used CD bin, don't hesitate for a second to buy it.
