At the Calexico show a couple weeks ago, the band threw a few lines from Bob Dylan's Silvio into the middle of "Victor Jara's Hands," turning the song a little sideways with a borrowed and entirely new vibe.
It's a trick I've always liked - not exactly a cover song, but a bit of an homage. Calexico just borrowed the "Silvio" chorus, weaving it seamlessly with their own song. I've seen other bands break out of a jam to perform the entiretey of another song within two halves of their own tunes, like Counting Crows do with Springsteen's Thunder Road.
But it's also a trick I don't see too often. I only find a handful searching through my iTunes library, and I wonder how much else I might be missing. Below are all of the live performances I have that use part or whole of another band's song. What am I missing? What other bands have done this? Is this cool or a gimmick? Does it spice up a song, or is a band better off just playing a whole cover?
