Boston Sings A Cappella Festival

Taking place in and around the city of Boston, BOSS is a three-day event featuring everything you’ve come to expect from an a cappella festival and more: an innovative spin on the scholastic competition on Friday, a full Saturday of classes and workshops plus a professional concert in the evening, and the exclusive LIVE presentation and announcement of the Contemporary A Cappella Recording Awards on Sunday.

All are welcome – groups and individuals, singers and non-singers. Purchase an All-Access Pass for admission to the entire festival (including the workshops during the day), or just come to be a fan at the concerts by purchasing tickets to the Scholastic Competition and Pro Concert.

The Real Group

The Real Group

Pro Concert Headliner

With the voice as their sole instrument, The Real Group have created a unique musical expression in the domain between jazz, pop and Nordic European choir music. The group was founded in 1984 and has been touring the world for more than 30 years.

Their combination of perfection and personal touch along with original songs has made them accessible to music enthusiasts in general as well as to the more demanding ear. Their wide repertoire and musical excellence have made it possible for the group to collaborate with symphony orchestras, jazz groups, popbands and notable artists such as Barbara Hendricks, Toots Thielemans and Sir George Martin as well as performing for The Royal Family in Sweden, opening the FIFA World Cup in South Korea and singing for state officials all over the world—including the Emperor of Japan.

The Real Group has produced 20 CDs in their own name, and they have also produced their own concert tours, TV programs and have been artistic directors for several a cappella Festivals around the world. In 2008 The Real Group initiated and hosted “The Real A Cappella Festival” and in 2012 “The Real Group Festival”—both in Sweden—attracting visitors from more than 20 countries. In 2015 they co-hosted the “Å Cappella” Festival on the island of Åland, focusing on vocal group singing, music sharing and positive encouragement.The Real Group also focuses on education, and through workshops and coaching aims to inspire singers and teachers around the world. Former baritone in The Real Group—Peder Karlsson—is one of the elements in the educational initiative and he was appointed as an Honorary Professor at the Royal Academy of Music in Aalborg & Aarhus in January 2016. To find out more about the group’s educational programs visit www.therealgroupacademy.se.




Pro Concert Performer

Iris is a vocal trio based in New York City that was formed in 2018. The group re-imagines classic songs beloved by all audiences. With just three voices, the group demonstrates the versatility of the human voice through unique and intricate vocal arrangements. Iris has had the opportunity to perform in a number of notable venues including Berklee Performance Center, Green Room 42 and Carnegie Hall. The group also competed in the International Championship of A Cappella Open and won first place in both semi-finals and finals. They also received Best Arrangement and Best Vocal Percussion in both rounds as well as Best Soloist in finals.



Pro Concert Performer

Impromptu is a new a cappella group based out of Indianapolis, Indiana. Formed from several Ball State alumni and local Indianapolis vocalists, Impromptu blends a unique sound from their fusion of jazz, soul, pop and R&B influences in their arrangements and performances. Their fresh takes on current and throwback hits of the last 2 decades have led them to perform on the international stage, winning VoiceJam in Arkansas and traveling to Taiwan for the Vocal Asia Festival last year.

Birdland Avenue

Birdland Avenue

Featured Performer

With a unique blend and contemporary style, Boston band Birdland Avenue creates evocative music that blurs the lines between pop, neo-soul, and R&B. The three birds—Evan Linsey, Kayla Pichichero, and Toria Rainey—started singing together in college and officially formed the band in 2016. From three-part harmonies to percussion, they produce every sound in their music with the human voice—using loop stations, samplers, and transformative effects to create their “neo-vocal pop” sound.

Their 5-time CARA nominated debut album Come Around was released in November 2018, featuring 8 original songs including fan favorites “Breeze Baby,” “Rabbit Hole,” and “On My Mind.” Sound of Boston calls the record a “a well-polished collection of radiant vocal pop that weaves together organic and synthetic textures without losing its human touch.” Rob Dietz (NBC’s The Sing Off, A Cappella Academy) says, “You know how #acappella folks are always saying we need more great original music from new groups with vision and a unique sound? Look no further—@Birdland_Avenue delivers.”
