These mash-ups are killing me on the inside

It seems that the logic behind much of today's mash-ups goes something like this: Do you like the Talking Heads? Do you like Radiohead? Then you'll love the Talking Radioheads: Thom Yorke singing over remixed Talking Heads songs. Actually that doesn't sound too bad. But for every bangin' mashup (see Dangermouse's Grey Album), there's a Q-Unit, where the Q stands for Questionable.

The best mash-up disk jocks have an ear that allows them to hear where the seams of disparate genres can be stitched together with effortless-sounding results. Here are some of those doin it right:

1. DJ Z-Trip: The first mash-up I ever heard was his mix of the Pharcyde's "Passin Me By" with Pat Benetar's "Love is a Battlefield". Like whoa. Here's Z-Trip mashing up Jigga Man with Jane's Addiction, J5 with Oasis, DPs and Green Day and more.

2. DJ bc's The Beastles: The Beatles are to eggs as Beastie Boys are to ???. If you said a) hot sauce, you are correct. How could this not be good, right? Right. Try on Sure-Bla-Di Shot-Bla-Da for starters, then head over to DJ bc's website for more excellent mashups of Buju and Stevie, and the White Stripes, Wings and Outkast.

3. Caps and Jones: Reppin Buffalo via Williamsburg, these dudes get an A+, and not just because Caps is in my fantasy football league. Their latest record, Moving in Stereo has been stuck in my head for months (that's right, the whole album is stuck) and I'm spreading the gospel like it's religion. For a sample that gives you the Fat Boys, Magnetic Fields, Jeff Spicoli and Neneh Cherry's Buffalo Stance, click here. Bddddddddddup - Stick Em!
