Help me, Statistical LJ

I know I should know the answer to this, but I'm failstats today...

Given that I have two series of numbers (a1, b1) (a2, b2) ... (aN, bN) I want to know the degree of correlation or the predictive value of aN.

Nu music

OK, that's a bad joke. Some of this is new and some is older stuff I just found. Also, I'm listening to some so-called "nu disco" about which more in a future blog, I expect.

APC did another of their multi-hour shows on Big City Beats. Quite a lot of good listening in here. The first part is a recap of a dozen of the remixes that appeared on APC in the past month. There's then an interlude of live mashing by Simon Iddol himself, but the best part is the last third, which is Copycat doing a live set with a bunch of his favorite mashes from the past few months. Copycat's style is hip and lively with a heavy dash of tribal and rhythm, making a good couple hours of listening.

Ruinmytune, which appears to be another name for Pheugoo, puts together a nice bounce mix. Given that it's built in part with Rozalla's "Everybody’s Free"(http://www.youtube.com/watch?v=6YgAw1G-4zY) which is one of my favorite vocal trance tracks. Pheugoo takes out the vocals, dropping the cheesy electronica in favor of a double dose of Calvin Harris's "Bounce" (http://www.youtube.com/watch?v=ooZwmeUfuXg). Kelis's vocals on the original Bounce are good, but I like the Rozalla/Harris combo better.

This mix is about a year old and I thought I had blogged it, but apparently not. Madmixmustang remixes two classics - Fatboy Slim's "Weapon of Choice" which gets remixed all the time - and Dead Kennedys' "Holiday in Cambodia". I don't think I've ever come across a DKs remix before and this one is insanely catchy.

Norwegian Recycling (http://norwegianrecycling.net) is a guy with a talent for multi-track mashing. He eschews the simple A/B pairings in favor of blending 4 or more related tracks into a new thing entirely. The YouTube page has a bunch of links to his stuff. Some of the more interesting pieces - like the "Don’t Stop Believin" currently on his site's home page - have almost conventional song structures, sometimes the same structures as one of the original pieces. As such they are less like the megamixes done by Lobsterdust and more like traditional pop songs.

Another one from about a year ago, Marc Johnce taking the then-popular "Duck Sauce" and Dizzee's "Flex" and putting together a remix workout song with Ray Krebbs' "The Gym". I've always thought Duck Sauce made more sense as backing track than as a stand-alone and Dizzee can rap above most anything.

DJ Steveboy's latest mix is "Downhome" and it's a nice blend of bluesy, funky, and danceable tunes. Lots of good phat horns.
