Vertical Form VI

The Allmusic review by Ron Wynn awarded the album four stars and states "This is a magnificent and critically acclaimed large band recording with the Swedish Radio Jazz Orchestra playing compositions and arrangements by George Russell, who also conducted. His music, with its intricate, unpredictable, and keenly structured pace, textures, and layers, are expertly played". The Rolling Stone Jazz Record Guide gave it five stars and called it "a live orchestral recording that captures Russell's innovative orchestration techniques in a stunning extended work".
