Frank Rein is a trombonist, multi-instrumentalist, composer/arranger, and educator living and working in Philadelphia. Originally from Princeton, New Jersey, Frank studied bass and tenor trombones at the University of the Arts in Philadelphia, where he began his career as a freelance musician. In his playing and writing, Frank creates performances with a strong sense of purpose and inevitability, two things that he strives to accomplish by approaching music with practiced mindfulness. That approach is not constrained to any one form or style of sound, and has led him to collaborate with artists in many genres. Frank is an active member of the large jazz ensemble Abstract Truth, the Balkan brass-inspired West Philadelphia Orchestra, the Neo-Soul collective Ode to Omni, the pop-reggae band Kings & Comrades, and the singer-songwriter Chris Paterno Band. He also collaborates frequently with Evan Cory Levine and His Singular Band, a hot jazz band, and the Space Whale Orchestra, a free jazz collective. Frank teaches a general music course in Philadelphia public schools with the Philadelphia Arts in Education Partnership.
