Big K.R.I.T. and Slim Thug connect on "Now and Then," a smooth new joint that will appear on DJ Wally Sparks' upcoming mixtape, SPKSMEN: Vol. 1. This ridin'-out track was produced by Krizzle, who only continues to impress with his talents on the mic and on the boards. Thug, of course, is no slouch, either.

You can stream the track by clicking the link in K.R.I.T.'s tweet below. The tape drops December 10.
