Mark Newton, whose roots go back to the Knoxville Grass and the Virginia Squires, continues to put out well-produced albums of solid Bluegrass with a contemporary edge. With new material from Tim O’Brien, Becky Buller and Dixie & Tom T. Hall, he has put together a very solid and enjoyable album, his 4th on Rebel. The Halls’ A BEAUTIFUL HOME is an especially nice song and a fine performance. TRAIN ON THE ISLAND, CABIN IN THE TREES, BLUES FOR BREAKFAST, LOSING YOU, SNOW COVERED MEADOW, CINDY,
