You probably scoff at classical music adaptations like techno remixes, jazz arrangements, weird electric guitar improvisations etc. Well, I'll suggest an instance where the remix improves on the original, namely the Baker Bros' Copland Died on December 4th, a remix of Aaron Copland's Danzón Cubano combined with Jay-Z's December 4th from The Black Album. MP3 page here (Soundclick registration required).
After listening to the remix, the original sounds lifeless and bland. But when Copland's melody and orchestration is combined with spirited (and sometimes reflective) vocals, the track is more than the sum of its parts. The effect is compounded when comparing it to the tediously slow recording conducted by Copland himself.
Note that Aaron Copland actually died on a December 2nd. I remember reading about it in the next day's NY Times while waiting for Caltrain on a cold morning in Palo Alto. From his obituary by John Rockwell:
Of many notable achievements, Mr. Copland's greatest gift was his ability to be both serious and popular, to adhere to the formal integrity and moral earnestness of modernism and also to espouse the generous accessibility of the dominant political mores of the 1930's and 40's.
