How deep and hypnotic can music get? This month's installment of Discreet Music seeks to answer that question in the abstract: from the smudged ambience of the Huerco S adjacent project Ghostride the Drift, to layered and disjointed new music from Tim Hecker and Logos, to the gauzy grooves of Earthen Sea. This is two hours of music to get lost in and be disoriented by.
