Work on African Noel, Coventry Carol, and We Wish You A Merry Christmas. Mainly work on African Noel, because more volume and groove would still be good. Remember, with groove, try to "feel" the rhythm just as much as you see it on the page. You should be listening intently to the tune and the rest of the band so that you’re grooving with them. You guys sound good, keep up the hard work!
