ANDY HEDGECOCK, MARIA DUARTE and ANGUS REID review Ackroyd & Harvey: The Art of Activism, The Lost Bus, A Big Bold Beautiful Journey, and Happyend

Signal-on-Sea
Irvine Beach
A YOUNG couple scream as they plunge into the water. A flock of seagulls descend on an overturned rubbish bin, surrounded by indifferent teenagers. A family’s picnic, complete with gas stoves and giant folding tables, becomes an object of envy as others struggle against the elements to get their barbecues going.
Close your ears and it could be just another sunny day in Irvine, one of several prime beaches on Scotland’s west coast in easy reach for the working class of the central belt.
But all around are tannoy speakers anchored in the sand, as if the nostalgic comparisons of our present predicament to the beaches of Dunkirk have culminated in a Blitz re-enactment in North Ayrshire.
