One of the things I love about Dylan is that he REFUSES to try and do a song the same way twice EVER. Whichever way he does this is is one of the all time great songs in rock/folk music. Here are two very different versions of the same song
Shelter From the Storm (by dylan)
Subterranean Homesick Blues (either by dylan himself, or there's a kickass version that Nickel Creek - bluegrass band - do where they play 'the fox' then half way through do SHB)
To Make You Feel My Love (Garth Brooks cover -I hate the new version by adele).
