CAMDEN — The Camden Opera House presents Camden Summer Sounds, a free outdoor concert series, every Sunday this month at 4 p.m. at the Camden Snow Bowl, 20 Barnestown Road.

The Aug. 14 concert celebrates blues music in Maine. The Midcoast’s Blind Albert Duo will open the show, followed by the Mark Miller Band, led by Maine native Mark “Guitar” Miller.

Miller comes by his nickname naturally, having picked up his instrument at age 6 to become a lifelong professional musician. His band has opened for B.B. King, Dickey Betts and Great Southern, Johnny Winters and Taj Mahal, as well as Pat Travers, Marcia Ball and Tab Benoit.

Vince “Blind Albert” Gabriel is a well-known local singer, songwriter, guitarist and bandleader. He ran sound for, and often sat in with, many blues greats for some 20 years of Rockland’s Monday Night Blues series. He and talented, ubiquitous local bassist Glen Dubose perform as a duo year-round, as well as with the full Blind Albert Band.

Camden Summer Sounds is sponsored this year by First National Bank and First National Wealth Management, the Town of Camden, and the opera house’s Community Arts Fund. No tickets are needed, just bring lawn seating and a picnic (water will be sold on site). Rain location, if forecast warrants it, will be the downtown Camden Opera House; that decision will be made by 5 p.m. the day before and announced on social media and camdenoperahouse.com. The series continues with country/bluegrass Aug. 21 and folk Aug. 28. Details are on the website.
