TOPSHAM – The third annual All Maine Barbershop Concert, featuring a cappella music sung in four-part barbershop harmony, will be presented at 7 p.m. Saturday, June 18, at the Orion Performing Arts Center.

Six choruses will each present a variety of ballads and upbeat tunes in barbershop harmony. Later in the concert, nearly 100 male voices from these six choruses will combine as The All Maine Barbershop Chorus for a medley of songs under the direction of a guest conductor, Bill Rashleigh.

Participating Maine Choruses will be Maine-ly Music Chorus of Bangor, Hillsmen of Norway-South Paris, Windjammer Chorus of Camden, Kennebec Valley Chordsmen of Waterville, Nor’easter Chorus of Brunswick and the Downeaster Chorus of Portland.

The concert also will feature two guest quartets. Appearing in the first half will be Men in Black, the Northeastern District Collegiate Barbershop Champions for 2002 through 2005. Known for their unique, youthful sound, they have embraced this hobby since formed while at the Hart School of Music in Hartford, Conn.

Men in Black has represented the district in the collegiate quartet competition at the international conventions in Portland, Ore.; Montreal; and Louisville, Ky. The ensemble will compete at the international convention in Salt Lake City in July.

RING! from Providence, R.I., will open the second half of the concert. Formed in August 2004, RING! quickly won the Barbershop Harmony Society’s Northeastern District Seniors Quartet Championship at the fall convention in Lowell, Mass.

At the society’s midwinter 2005 convention at Jacksonville, Fla., RING! earned a Top 10 finish against 23 of the best seniors’ barbershop quartets in the United States.

The guest conductor is a music specialist with SPEBSQSA Inc., the Barbershop Harmony Society. Rashleigh works with barbershop chapters throughout North America, specializing in chorus development. He earned a bachelor’s of music degree in voice and a master’s of music degree in conducting performance from the University of Nebraska at Omaha. He lives in Racine, Wis.

A portion of the proceeds will go to an area charitable organization.
