Extension was the last of 3 unique Blue Note sessions led by the singular saxophonist George Braith in the early 1960s. The album was rooted in soul jazz – with Grant Green (guitar), Billy Gardner (organ), and Clarence Johnston (drums) – but Braith’s adventurous spirit led the music into unexpected realms on memorable originals like “Nut City.” Blue Note Classic Vinyl Series is all-analog, mastered by Kevin Gray from the original master tapes, and pressed on 180-gram vinyl at Optimal.
