VoXX: Voice of Twenty is well-known for dressing in black and putting on serious concerts of mostly early a cappella vocal music. But members of the group will change their focus (and their outfits) to put on a completely different show Friday and Saturday, Sept. 28 and 29.

Called “Solo VoXX: Fighting Hunger with Songs” the revue will showcase some of the many other hidden musical talents within the group. There will be some classical works (of course) plus folk, jazz, pop, rock ‘n’ roll and maybe even some audience participation. The concert is a fundraiser; a percentage of the proceeds will be donated to help feed those in need in Knox and Waldo counties.

The “Solo VoXX” concerts, both at 7:30 p.m., will be presented Friday at Northport Music Theater, 851 Atlantic Highway/Route 1; and Saturday in the Parish Hall at St. Thomas’ Episcopal Church, 33 Chestnut St., Camden. Admission will be by donation at the door; audience members also are encouraged to bring a non-perishable food item or two to be donated to local soup kitchens. Refreshments will be sold during intermission. Beneficiaries of money and foodstuffs will be the Greater Bay Area Ministerium (GBAM) Food Cupboard, part of the Belfast United Methodist Church; and the Camden Area Christian Food Pantry and the Loaves and Fishes Soup Kitchen at St. Peter’s Episcopal Church in Rockland, both via St. Thomas’ Episcopal Church.

The evening will feature original works and improvisations by group members plus songs in the classical vein; and folk, jazz and popular tunes. Group members and special guests will chime in on guitar, percussion, piano, mandolin, bass, harpsichord, winds, cello and vocals. The subject matter will cover hunger and plenty, love and loss, peace and change; and the evening will culminate with a group finale of Leonard Cohen’s “Halleluia,” with some special VoXX twists.

“Last year’s Solo Voxx fundraiser was a great way to help a good cause — and to stretch our wings between our regular full-group concerts in July and January. There are no limits on the types of music members can perform, so the result is going to make for quite the varied evening,” said music director Gregory Moore.

VoXX is unusual in that it is a collectively run, all-volunteer organization. Membership is by audition (the group is currently seeking some new members), and singers come from all walks of life. Members share the responsibility of bringing music selections to the group and can take turns teaching and leading. The group has built a strong following and has performed in many venues around Maine.

VoXX: Voice of Twenty is currently in rehearsal for its ninth annual late-January “Musike for the Nywe Yeare” concerts, three performances of works — many of them new to the group — built around a Winter Reflections theme. The concerts will be held during the weekend of Jan. 18 through 20. One will be in Belfast, one in Camden/Rockport (venues and times to be announced); and one at the historic Phippsburg Congregational Church to perform as part of its winter music series. If snow dates are required, they will be on the following weekend. For more information about VoXX’s performance schedule or for an audition application, call 236-9413 or visit voiceoftwenty.com.
