As a leader, Cowell debuted on the Arista-Freedom label with 1969's Blues for the Viet Cong, followed that same year by Brilliant Circles. He then moved to ECM for 1973's Illusion Suite. Also in the early '70s, he worked regularly with trumpeter Charles Tolliver, with whom he co-founded the Strata East label. Consequently, he delivered several highly regarded albums for the label, including 1974's solo piano date Musa: Ancestral Streams and 1975's Regeneration. Also during this period, he played regularly with the Heath Brothers and continued recording, releasing a handful of solo piano albums for Galaxy Records, including 1977's Waiting for the Moment and 1978's Equipoise.
Beginning in 1981, Cowell started balancing his time between performing and working as an educator, first at CUNY's Lehman College, and then spending several decades at Rutgers University in New Jersey. During these years, however, he remained active in the studio and developed a fruitful relationship with SteepleChase Records, which issued such well-received albums as 1989's Sienna, 1993's Angel Eyes, and 1997's Hear Me One.
More albums followed for the label, including 2010's Prayer for Peace, which featured the pianist's daughter Sunny Cowell on vocals. Two years later, he was joined by former Rutgers students bassist Tom Dicarlo and drummer Chris Brown on It's Time, followed by 2013's Welcome to This New World with the Empathlectrik Quartet and 2014's Are You Real? In 2017 he delivered his 15th album for SteepleChase, No Illusions, featuring saxophonist/flutist Bruce Williams, bassist Jay Anderson, and drummer Billy Drummond. Stanley Cowell died on December 17, 2020 in Dover, Delaware at the age of 79. ~ Matt Collar, Rovi
