Camden Public Library’s Summer Music series invites everyone to join electronic music act Quantum for a special, free performance Sunday, Aug. 14, at 1 p.m. at the Camden Amphitheatre, Atlantic Avenue.

Quantum is the Midcoast duo of Jason Dean and Michael Whitehead, exploring ambient electronic sounds with Dean on vocals, drum machines and keys; and Whitehead on bass and effects. Together, they produce soundscapes to move both mind and body.
