UGK - "Bubble (Clean Remix)" | zShare
from It's Supposed to Bubble promotional CD single (Jive, 1994)
Here is one more version of the "It's Supposed to Bubble" single. The CD version isn't much different from the more well-known vinyl press, except for the fact that the sound here is CD quality, as opposed to the quality you would otherwise get from a vinyl transfer.
The single includes cleans versions of the original and the remix, plus their instrumentals.
Props to Nils from www.HASSMUSIK.com for the .wavs from the single.
[UPDATE: Here's some hi-res scans of the single's front label, back cover, and CD.]
