Folk purists would doubtless be appalled to learn that Seth Lakeman's songs are available as ringtones. But it clearly shows the former Mercury Music Prize nominee's crossover appeal, and this energetic tour finale marked his arrival as a mainstream pop star who just happens to play the fiddle.

With flashing lights and pounding percussion, this was more like a rock show than an evening of politely rootsy songs. Lakeman punished his violin from the off, and he stomped around the stage during Riflemen of War as if in the mood for battle himself.

This rugged folk superstar from Devon could also do tender, though, as on the single The White Hare. Switching to acoustic guitar, he summoned up a heartfelt melody alongside lyrics based on a West Country legend about a woman murdered by her husband who returns in the form of a hare to take her revenge.

Traditional tales and local history form a large part of the Lakeman canon and he proudly introduced the heroic ballad King & Country as a tribute to his grandfather.

He dedicated the rambunctious drinking song How Much to the bar staff, and it became an obvious crowd-pleaser thanks to the urgency of the rhythms produced by his talented band.

Yet it was Lakeman's solo version of Kitty Jay that really enlivened the audience. His violin workout became a furious, foot-stomping performance that left the fans in awe and Lakeman drained and dripping with sweat.

This was folk at its most formidable.
