New Yorker Ryan Keberle is in three bands. He's been around the world with singer/songwriter Sufjan Stevens. He's been in the studio with David Bowie, Alicia Keys and David Byrne. He serves as Director of Jazz and Brass Studies at Hunter College. Playing jazz in Manhattan for the last 15 years has only made him more conversant in his particular field: South American music. On 'Azul Infinito' (Greenleaf Music), he stretches the boundaries of music from Columbia, Argentina, Brazil and Peru.
