I've heard on the listener-supported local radio station a group called "Tom Morrell and The Timewarp Tophands" that are pretty good - they have several CD's out. One cut in particular, "Rollie Pollie", I've heard several times as well as an old version (possibly Bob Wills?) and they compare favorably. Since they're so faithful to the original I don't know that you'd classify them as new, but the recordings are modern at least.
