'Yanni Voices' tour heading to the Arena

Yanni has called the human voice "the most expressive instrument known to man."

The self-taught pianist, keyboardist and composer, known for his classical, instrumental music, has paired his work with the voices of four singers for "Yanni Voices," his first studio release in six years.

Debuting at No. 20 on Billboard's Top 200 and No. 1 on the New Age chart, the album has inspired a tour, which opened April 10 in Fort Lauderdale, Fla.

Yanni and his vocalists - Chloe, Nathan Pacheco, Leslie Mills and Ender Thomas - will present "Yanni Voices" live at the Arena at Gwinnett Center on Saturday night.

The "Yanni Voices" album and tour are the first time the Greek musician has prominently featured vocals and lyrics to his compositions.
