The tussling vegetables in Mal Dean’s cover-sketch somehow befit perfectly this extraordinary duo of Bailey and the great Dutch drummer Han Bennink. Recorded in London in 1972, Incus 9 was their second record (after an ICP in 1969), becoming a blueprint and inspiration for generations of free-improvisers. It is paired here with a brilliant session from the following year, with the same power and friendly combativeness, and oodles of creativity, technique and humour. It’s obvious how much they loved playing together.
