The Novel Jazz Septet will return Thursday, July 7, at 7 p.m. to enliven the Camden Amphitheatre outdoor music season with the swinging music of the great American jazz composers Duke Ellington and Billy Strayhorn.

The concert is part of Camden Public Library’s Summer Concert Series, supported by help from the Reny Charitable Foundation. The concert is free, but the hat will be passed to help with travel expenses for the band. Concertgoers should bring blankets or lawn chairs for comfortable seating.

The combo performs well-known compositions plus vintage gems recently unearthed from original scores at the Smithsonian and re-interpreted, traveling far and wide to keep the spirit of Duke and Swee’Pea alive and swinging. The musicians of Novel Jazz have been performing “straight-ahead jazz” around Maine and New England for more than three decades. The band members hail from all over Maine — Belfast, Buxton, Chebeague Island, Gardiner, Newcastle, Thomaston and Vassalboro.

Novel Jazz performs regularly at the Skidompha Library in Damariscotta in an effort to keep jazz alive in the state. A decade ago, they embarked on a project to go through the massive archive of compositions by Duke Ellington and Billy Strayhorn — who wrote about 2,500 pieces between them — to transcribe some lesser-known gems for the band and reinterpret them with a 21s- century sound. Their first CD was released in 2008, another in 2011 and the band released its third CD, “Novel and Novelle: More unearthed treasures by Billy Strayhorn and Duke Ellington,” in June 2015. Several two-hour programs dedicated to Novel Jazz have been broadcast on Maine Public Radio’s “Jazz Tonight” over the years.
