The Dennis Cove Band  http://www.denniscoveband.com/home.php consists of Carl Hazelwood on guitar, his son, Chris Hazelwood on mandolin, Don Anderson on standup bass and Dean Burchett on banjo. Mary and I first heard them at Thompson's Produce, near Embreeville, TN., at one of their Saturday night shows and we were delighted at the traditional Bluegrass music and excellent harmonies. I spoke with them after the show and they all turned out to be wonderful fellows.
They have a busy schedule which is starting to fill in even more each week. Here's a partial listing of where they'll be playing:
