Never owned a guitar wolf album, but I thought they were great in Wild Zero and I hope to see them live one day. Peelander-Z isn't a "good" band either, but I like their live energy.
I once convinced Myself they were an amazing band just really rough around the edges, but they actually really suck. Their latest sounds rough and garagey and is legit good, but this is Wyld Stallyns bad.
