Andrew Oliver is a pianist, composer, and bandleader from Portland, OR. His main projects include the Kora Band, fusing jazz and west African traditions, Tunnel Six, a Canadian-American collective sextet, the Ocular Concern, a minimalist jazz ensemble, and the Portland Jazz Composers' Ensemble, a 14-piece group commissioning and performing new music by local composers as well as operating a grassroots record label, PJCE Records.

His music draws on influences ranging from Jelly Roll Morton to traditional west African kora music to tango and many points between but the overarching aesthetic lies somewhere within the melting pot that is contemporary jazz.
