The whole "remix" thing is misdirected. For example, I was momentarily hyped when Madlib started doing the whole Yesterday's New Quintet instrumental stuff, but I came to realize the remixes sound flat and are not as satisfying as simply hearing the original song. So I did not buy Madlib's Blue Note effort, and generally avoid "remix" albums. I'd rather hear it raw.
FWIW, I bought the Verve comp "Unmixed" for a nice clean version of Nina Simone's "Feeling Good."
I won't buy this Charlie Parker thing either.
I much prefer it when DJs combine oddball snippets to create original compositions, rather than merely reducing a complex work into hip hop measurements. The artistry of sampling is the chance taken in juxtapozing unrelated sounds; in searching for original sounds, intriguing drum loops, vocal samples, etc.; in creating unorthodox aural collages.
