Edinburgh 2013: James Acaster: Lawnmower

Last year James Acaster beguiled his way on to the Foster's Edinburgh Comedy Awards shortlist with an artfully crafted study in mild lunacy. This year offers something similar, equally well-shaped, and equally kooky, but it sails so close to the wind of being inconsequential that a cloud of uncertainty hangs over the room for portions of the show.

Album: Thea Gilmore, Strange Communion (Fullfill)

Decent Christmas albums don't come along that often – it's ten years since Low's remarkable Christmas, while the last unqualified success, Aimee Mann's One More Drifter in the Snow, arrived in 2006 – so we should celebrate an undertaking as poised and thoughtful as Thea Gilmore's Strange Communion, the best of this year's batch of seasonal offerings.

Coming Soon: Yoko Ono shines in her own right

Moving eastward and backward from the Royal Academy's Byzantium show comes Babylon – or, perhaps, Babylon! – at the British Museum (020-7323 8181, 13 November-15 March). When Constantinople was a twinkle in antiquity's eye, Babylonia was already a wonder of the world; a place of ziggurats, legal codes and Hanging Gardens. If it peaked early – c. 600BC, in fact – the city-state remained dangerously attractive to invaders. The latest of these are George W Bush's troops, whose addition to Babylon's history has been to drive tanks through the remains of its 2,600-year-old Imperial Way – a woeful chapter shown alongside the tiled glories of Nebuchadnezzar. So much for progress.
