Gathering key 1965-66 New York sessions, this 2-CD set traces alto saxophonist Marion Brown's emergence in the free jazz vanguard through Capricorn Moon, Why Not? and Burton Greene quartet recordings, with Alan Shorter, Bennie Maupin, Stanley Cowell, Henry Grimes, Sirone, Rashied Ali and others shaping music of lyrical urgency, open-form momentum and evolving collective freedom.

Saxophonist Noah Howard's move from New Orleans to New York City brought him into the circle of early 60's free jazz players including Albert Ayler, joining Sun Ra's Arkestra, and performing at Slug's Saloon; this release reissues two ESP albums, his working band's 1966 Quartet album, and the extended and interestingly orchestrated sextet album, At Judson Hall.
