Na Hoku Hanohano award-winning musicians Jeff Peterson and Riley Lee will be celebrating their best instrumental recording win with a Friday concert.

Much of the performance will come from their Mountain Apple CD "Haleakala," but guitarist Peterson is expected to play some solo slack key and shakuhachi grand master Riley Lee will also play melodies on the bamboo flute.

The concert is 7:30 p.m. Friday Hawaii Public Radio's Atherton Performing Arts Studio at 738 Kaheka Street. Tickets are $25 general, $20 for HPR members and $15 for students with ID. Reservations can be made at 955-8821.
