We’ve posted many times this past few weeks with updates about CMT.com’s online video competition for unsigned artists, with the winner being flown to Nashville to record a segment for CMT.com’s Studio 330 Sessions.

Our focus has been on the bluegrass or bluegrass-related entries, and we are delighted to report that Buncombe Turnpike, with the sole bluegrass video in the 3rd round of 16 competitors, has made it through to the the 4th round of eight.

Mimicking the NCAA basketball tournaments, CMT’s Music City Madness has paired videos in head-to-head match ups in each round, starting with 64 entries selected from those submitted for this contest.

This 4th round, which will select the Final Four, allows online voting until March 19. If you would like to see a bluegrass band in the semi-finals, head over to CMT’s Music City Madness site and cast your vote.
