Deep Gap, N.C. native Arthel "Doc" Watson is a national treasure, and he's got a National Medal of Arts and seven Grammys--including a recent Lifetime Achievement Award--to prove it. Oh, and he's also king of the flattop guitar. (UNC's got a nice little page about him at www.ibiblio.org/DocWat/DocWat.html.) This time around, Doc and his grandson, Richard Watson, along with David Holt are on a "Hills of Home" tour. They stop by to do some pickin' at the Carolina Theatre on Friday, Aug. 27. The show starts at 8 p.m. Tickets start at $28.50. For information or to order call 560-3030 or visit www.carolinatheatre.org.
