"Double Shot" is a neat cover of the Swingin' Medallions' song, but I can't say it's their best one, not even close. I don't really like the original song anyway, so yeah.
"Loss of a Loved One" is one of my favorite tracks on the original album, and it's nice to have an extended version of it (even though the extra parts aren't really memorable).
Now, the instrumental of "Kiss of Flesh" is what gets me, 'cause I effin' love that song to death. It's so menacing (which really fits the part of the story it's based on), and it keeps you paying attention during the whole nine minutes of it. It's easily one of my favorite Residents tracks of all time. This record isn't really essential. Like I said, the only part where it really gets good is "Kiss of Flesh", and you can easily listen to it by getting the soundtrack instead.
