Internationally renowned Spanish saxophonist-composer Xose Miguelez's latest album, Ontology, began with his research on traditional Galician music. That research led him to a discovery of a recording by ethnic musicologist Dorothé Schubart of a ballad sung by his own great-aunt Amparo almost 40 years ago in a village in the Galician hills named Cerdedelo-Laza. The first-four note motif at the beginning of this ballad is the root of all Miguelez's compositions on this album. Ontology was recorded with Miguelez's modern jazz quartet, plus saxophonist Matt Otto, who produced the album, on three of its tracks.
