The musical partnership between mandolinist Paul Glasse and guitarist Mitch Watkins has lasted more than 30 years and weathered a ton of extracurricular activity, from tours with Leonard Cohen and Lyle Lovett (Watkins) to appearances with jazz bass hero Gene Razey and shows at the Kennedy Center (Glasse). But the pair’s uncanny chemistry holds true no matter how much time apart they spend, deftly putting a Lone Star twist on the expert blend of jazz and bluegrass known as “newgrass.” Accompanied by versatile bassist Chris Maresh and drummer Mike Gordon, the duo brings the heat.
