The Bay Chamber Concerts Summer Concert Series will present three concerts in its fourth week. They begin Thursday, Aug. 4, at 7:30 p.m. with Music for Winds at the Rockport Opera House, 6 Central St.

Danish composer Carl Nielsen’s Wind Quintet anchors this program of music from composers hailing from across Europe, performed by some of this country’s finest young wind performers. Musicians for this piece include James Austin Smith, oboe; Julietta Curenton, flute; Alicia Lee, clarinet; Adrian Morejon, bassoon; David Byrd-Marrow, horn; and artistic director Manuel Bagorro on piano.

This concert is offered in memory of renowned arts patron Mary Curtis Bok, who founded the Curtis Institute of Music and for many years oversaw the Curtis summer music colony in Rockport. As Rockport is celebrating its 125th anniversary this week, it is fitting to honor Bok with this performance.

On Friday, Aug. 5, at 8:30 p.m. at Union Hall, 24 Central St., Bay Chamber Concerts presents an eclectic program that gives audience members a chance to get closer to these noteworthy musicians and experience some fascinating wind repertoire. At the core of the Café Nights program is Britten’s Six Metamorphoses after Ovid, a work for solo oboe describing characters from Roman mythology, each with a narration. The piece is performed by the acclaimed James Austin Smith. The Café Nights Series at Union Hall is generously sponsored by Mazie Cox and Brinkley Thorne, of Rockport.

Tickets for either wind concert are $45, $10 for those younger than 25. For more information or to purchase tickets, visit baychamberconcerts.org or call the box office at 236-2823.

On Sunday, Aug. 7, at 5 p.m., as part of the culminating celebration of Rockport’s 125th anniversary, Bay Chamber will present the Irene and Billy Wolf memorial concert, Jazz on the Water. This free outdoor concert in Rockport Marine Park is part of day-long festivities and features the Creative Ensemble Collective with guest saxophonist Donnie McCaslin, performing jazz favorites and original works on the lawn just opposite the Harbor Master’s office. Opening the afternoon’s musical festivities at 4 p.m. will be Rockport’s very own Push Farther Project featuring Alex Wilder and William Foote, guitars; and Nora Willauer, cello, performing original songs.
