The Coalcracker Chorus is set to present its 60th Annual Harmony Extravaganza on Sunday, Aug. 29 at 2:30 p.m. at the Tamaqua Area School District Auditorium.

The chorus originated as the Mahanoy City Chapter of the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America (S.P.E.B.S.Q.S.A.), which is now known as the national Barbershop Harmony Society. Over the years, membership expanded outside of Mahanoy City and now includes members from throughout the region.The chorus' mission is to perpetuate the old American Institution, barbershop harmony, and to promote and encourage vocal harmony and good fellowship among their members. Practices are held on Mondays at 7:30 p.m. in Barnesville.In addition to the performance by the chorus, the Harmony Extravaganza will also include appearances by two guest quartets.The featured quartet is 'Round Midnight, an award-winning a cappella quartet of music educators from the Long Island/Manhattan area of New York.While 'Round Midnight sings primarily in the barbershop style, its eclectic influences range from jazz to classical and everything in between. They have been featured in an array of showcases, contests and educational workshops spanning the United States from New York to California.'Round Midnight is the Barbershop Harmony Society's current 2010 Mid-Atlantic District Quartet champion. They are also an international semi-finalist for the second year in a row at the Barbershop Harmony Society's contest held in early July in Philadelphia.'Round Midnight was a national finalist in the Hamony Sweepstakes, as well as a two-time "audience favorite" award winner at the New York Regional Harmony Sweepstakes and was the 2006 champion at that event.The members of 'Round Midnight are Wayne Grimmer (lead), Larry Bomback (tenor), T.J. Carollo (baritone) and Jeff Glemboski (bass).The second quartet scheduled to perform is Three Lads & a Dad, an up and coming western division quartet,For tickets and information, contact Frank Walton, Coalcracker Chorus Marketing Director, at (570) 668-2325.
