First let me start by saying that I have listened to Gwar a good portion of my life, and have enjoyed every album of theirs in a different way. To make my opinions unbiased about Gwar, I have thought they have dramatically decreased their potential in the last two albums, War Party and Beyond Hell. This being said, I can say that I thoroughly listened to the ENTIRE Lust In Space album. I enjoyed it from start to finish.
There were a few points when I was literally laughing my ass off because of the skit in the song "Where Is Zog?". I really enjoyed the tracks "Let Us Slay", "Metal Metal Land" and "Power Shot" as well, which were (in my opinion) the best tracks on the album. I can say without a doubt that "Metal Metal Land" had the best lyrics like "where everyone must rock and every girl sucks every cock" (more or less).
The guitar was mediocre however, the solos just sounded detuned and noise/ambient like squeeling all the time. That was the downfall of this album, which sucked, because I was hoping Gwar would pull some technical stuff.
The bass in Lust... was unheard, which is unusual for Gwar, because usually you hear Beefcake's bass alot.
The Drums were superior to the last two albums and I was impressed at how Jizmak got some fast double bass, then switched to polymeters in a few seconds. It was intense.
Overall I'd say buy the album, because if you like Gwar, you'll enjoy this album. Steal money from the Pentagon if you have to.
TL;DR version: 86.5/100
