Lucian Ban is a jazz pianist and composer who in recent years has become a key figure on New York’s downtown jazz scene. This album is devoted to the work of Romanian classical genius George Enescu, the violin virtuoso who taught Yehudi Menuhin, and whose compositions looked westward to the regular classical repertoire and eastward  to oriental music, while being rooted in his homeland’s folk traditions . . . Fast trumpet solos with tabla rhythms turn into a seesawing Enescu folk-melody, and percussive Indian chanting is prodded by Herbie Hancockish piano chords and then raw free-jazz sax. It’s a rare combination of uninhibited but coherent solo and collective improv, shrewd arrangement and dazzling thematic writing.
