I would not only agree whole-heartedly that the Grateful Dead are the inverse of Devo in the cover song department, but just in general. I think the two bands are clearly the far ends of some kind of music spectrum, complete opposites in every way. What would you call such a spectrum?
My entries in the “worst cover song ever” department are 311 covering The Cure’s “Love Song” and The Wallflowers covering Bowie’s “Heroes”. Dear douchebag bands: Own your douche status. Do not take a piss all over the great artists of the past that you will never be.
Also, Michael, thanks for introducing me to this website. That’s the sort of thing that makes me love the internet. The world is a better place because it has a database of songs that employ the “truck driver’s gear change”.
