The Bach Choir of Bethlehem is expanding its “Allentown Bach at Noon” series to three concerts on second Tuesdays 12:10-1 p.m. June 14, July 12 and Aug. 9 at St. John’s Lutheran Evangelical Church, 37 S. Fifth St., Allentown.

Admission is free. Reservations are not required. A free-will offering will be taken.

Doors open at 11:30 a.m. Attendees are encouraged to arrive early. Parking is available in the Allentown Parking Authority’s new Community Deck, Sixth and Walnut Streets, one block west of the church.

The inaugural “Allentown Bach at Noon” performances in June and July 2015 drew capacity crowds to St. John’s Lutheran Church in downtown Allentown with audience members including downtown residents and business people as well as visitors from out of town. Leaders of the renaissance in Center City Allentown have responded enthusiastically to last year’s concerts and to the planned expansion of the program.

Bridget George, Bach Choir executive director, said that The Bach Choir is grateful to the corporate sponsors who are helping make this gift to the community possible, including the Rider-Pool Foundation, Air Products, City Center Investment Corp., Cross America Partners, Dunne Manning Inc., Alvin H. Butz, the Century Fund, and Norris McLaughlin & Marcus, P.A.

Each free 50-minute concert includes one choral and one instrumental work introduced by Bach Choir artistic director and conductor Greg Funfgeld with an engaging talk about the music to be performed.

Here’s the “Allentown Bach at Noon” Summer 2016 schedule:

June 14:The festive opening concert features members of The Bach Choir performing with Philadelphia Brass, additional brass and percussion, and Tom Goeman, organist. The program opens with a chorale from Bach’s Cantata 130 “Herr Gott, dich loben alle wir” (“Lord God, we praise thee ev’ry one”) followed by the one-movement Cantata 118, “O Jesu Christ, mein Lebens Licht” (“O Jesus Christ, my life and light”). Philadelphia Brass offers selections from Bach and Vivaldi. There’s a reprise of the Motet BWV 230 “Lobet den Herrn, alle Heiden” (“Praise the Lord, all ye nations”) from the Family Concert-Youth Choirs Festival with singers from The Bach Choir again joined by singers from four youth choirs: The Bel Canto Children’s Chorus of the Bach Choir of Bethlehem, Berks Youth Chorus, Charter Arts Touring Choir and the Nazareth Area High School Chorale. The program ends with Vaughn Williams’ setting of the “Old Hundredth Psalm Tune,” with brass, percussion, the St. John’s Church organ, and audience members joining the choirs in singing.

July 12:The program features one of Bach’s best beloved cantatas BWV 140 “Wachet Auf!” (“Sleepers Wake”) with members of The Bach Choir and Bach Festival Orchestra joined by soloists Rosa Lamoreaux, soprano, and Steven Combs. Also featured is the virtuoso young pianist Kristina Moditch playing two preludes and fugues by Bach and the “Pathetique Sonata” of Ludwig van Beethoven.

Aug. 9:The summer series concludes on a light-hearted note with Bach’s “Coffee Cantata” BWV 211, including soloists Leslie Johnson and Bran Ming Chu, and “The True Story of Cinderella” by Warren Martin (1916-1982), a Westminster Choir College graduate and faculty member for the annual May Day Celebration.
