The Chicago rock band Twin Peaks spend half their time as a chugging power chord factory and half as a winsome power-pop band. Their first album, Sunken, which ran a compact twenty minutes and was as refreshing and ephemeral as a popped Schlitz can, contained hints of both. Their second, , is more than twice the length, in which they seem to be offering two distinct versions of themselves: in one, they're good-times party rockers, and in the other they're heartbroken sweethearts. You could cull down to make one nine-song version of either album, and one would be just okay and one would be really good.
