"Space Gun wraps up with "Evolution Circus", showing a sludgier, less poppy side of Guided by Voices than the album's brighter moments. Pollard just doesn't want to take it easy on his fans, does he? Instead of sifting through his material to give you only the most immediately likable stuff, he gives you everything in bulk. Then it's up to you to go digging. I find Space Gun to be about two-thirds great. Those great moments are what keeps people coming back for more, to continue digging and to find that perfect Robert Pollard song. Does it already exist? For all I know, it could be right here on Space Gun".
