I’d recognize that 17/16 pattern anywhere! Wonderful to hear *just* the "rhythm section" especially the modulation in the second half of the piece when Bill switches the percussion from the more genteel slit drum accents to the heavier boobams, rototoms and distinctive Bruford snare. Adrian makes a ’special guest appearance’ at 3:18 onwards in this bass & drums mix (while Robert’s precise picking is heard faintly in the background to help hold it all together).
