Camden Rotary’s annual Music by the Sea has a top-notch, varied lineup this year, truly offering al fresco tunes for everyone Monday, July 4. The free musical performances begins at 2 p.m. at the Camden Amphitheatre and Harbor Park and goes right up to the 9 p.m. fireworks display presented by Penobscot Bay Regional Chamber of Commerce over the water.

Bringing lawn seating such as blankets or beach chairs is encouraged, as bench seating is limited. As always, the Rotarians will have picnic fare for sale.

Up first, from 2 to 3:30 p.m., is Mes Amis, an acoustic Gypsy jazz quartet based in Central Maine that features guitarist, vocalist and composer Steve Lynnworth; Shane Ellis on clarinet and saxophone; Harry Richter on rhythm guitar; and Wells Gordon on upright bass. The group plays an infectious mix of traditional Gypsy, Latin and American jazz standards, along with many original compositions. Mes Amis recently released its debut CD.

Independence Day calls for Sousa, Broadway and Big Band music and from 3:30 to 4:45 p.m., the Casco Bay Wind Symphony will comply. This 70-member ensemble was a huge hit at last year’s Music by the Sea celebration and is back by popular demand. The nonprofit community wind band, based in Gorham, performs regularly around Maine and New England. More than a third of the members are music educators and professional musicians, while the majority of the members continue their music as an avocation.

Brooklyn-based Roosevelt Dime, fronted by Camden native Eben Pariser, will play from 5 to 6:15 p.m. Roosevelt Dime combines the feel-good groove of classic R&B with acoustic Americana instrumentation. Pariser brings the soulful vocals and semi-hollow electric guitar work; and band co-founder Andrew Green contributes piano-inspired banjo style, equal parts boogie woogie and bluegrass. They lock in with the New Orleans clave rhythms of Tony Montalbano's drums and Craig Akin's syncopated upright bass to deliver original songs of hope, love and conviction.

After a break for supper-ing, the final set will run from 7:45  to p.m. The Lowdown promises great harmonies and tasteful arrangements to energetic performances of American folk and roots music. Singer/songwriter David Dodson’s compositions, which run the gamut of American styles from folk to country, blues and rock, range from poignant to hilarious; and singer/songwriters John and Rachel Nicholas create music that speaks to the heart. John and David both play acoustic and electric guitar, with Rachel on percussion. Lifelong musician Mike Nickerson supports this soulful ensemble on upright bass and blues harp.
