But even though modern folk is far more diverse than cliche would have it, the F-word barely goes a fraction of the way to describing the rollicking output of this 11-headed, 22-armed, many-instrumented monster.

They're set to wildly inventive arrangements as likely to hinge on funk bouzouki or polka violin as any of the staple folk instruments.
Highlights here are a riotous stomp through Lillibulero, a swaggering take on the old miners' song Byker Hill and full-steam-ahead shanty Go My Way which proves Bellowhead can do unabashedly epic just as well as they do raw'n'rowdy.
Another triumph for Britain's most giddying collection of folk talent.
