Barry and Valerie have been performing together since 1982. With the kind assistance of Nobuco “Cobi” Narita (The Universal Jazz Coalition) and countless others, they went from local libraries, parks, museums, and New York City Public schools to the international stage, where, in 1996, they performed in the Kobine Festival of Traditional Music in Lawra, Ghana, where they were honored as the first non-West Africans to be awarded a first prize.
As a duo, they have performed at festivals worldwide including The Percussive Arts Society International Conference (1994, 1996, 1999, 2000, 2001); The New Music Festival (Leon, Mexico); Semana Internacional de Percusiones (Mexcio City); El Primer Festival Internacional de Marimbistas (Chiapas, Mexico); The Bath Festival (Bath,England); and Arts Alive (Johannesburg, South Africa). In July 2005, they were performers and clinicians at the 25th Fairbanks Summer Arts Festival, and have been invited to return in 2006.
They co-direct the multi-instrumental/vocal quintet Mandara, which has performed at such venues as the Kaisuka Festival (Japan), Lincoln Center, and The Kennedy Center.
