Christmas Is: December Duets

Together, Mike Renzi and Jim Porcella have produced a sublime collection of simple, heartfelt holiday tunes, all done with delightful originality. Renzi adds the perfect decor to Porcella’s warm yuletide voice, especially on the tender “Christmas Is,” the minor key magic of “Snowfall,” and a peaceful take on Irving Berlin’s “I’ve Got My Love to Keep Me Warm.” (Whaling City)
