The Long Run, Mattan’s latest project, features several his regular musicians, including Toki Stern (Rhodes), Yoni Ben Ari (bass) and Joca Perpignan (percussion), with special guest Nitzan Bar (guitar). Mattan’s music has been described by Yossi Harsonsky, Senior Music critic at Maariv, as, “flowing, bright and listener friendly…his flute sound is clear, crispy and melodic, and the Israeli-Brazilian mix is the ultimate contemporary jazz sound, spiced with warm, unique flute sounds…Klein's virtuoso improvisation lifts Jazz-flute playing to new heights."
