Rock Island’s own Randall Hall dropped a transfixing full-length album titled Oracle in mid-June that documents a cycle of his extended saxophone experiments and electro-acoustic compositions – all with the intent to, as he explains, “delve into the mythic, the esoteric, and the apophatic.” Loaded with fierce atonal sax shred, passages of freewheeling improvisation in more consonant modes, and interstitial segments of processed spoken word and electronics that build on his central theme of ancient Greek mysticism, Oracle lands as a fully realized and diverse statement of purpose from Randall Hall with seemingly few other precedents in the Quad Cities scene.
