Anselm Kiefer
White Cube Mason's Yard, W1 Royal Academy of Arts, W1
In the White Cube's West End space, a single installation, Palmsonntag, fills the ground floor, with 18 paintings lining one wall and a gangly palm tree lying across the gallery. Organic materials like flowers enliven a series of dense, complex landscapes. Around the corner at the Royal Academy of Arts, two multistorey concrete towers loom up from the classical surrounds of its courtyard. Though it lacks some of the nervy intensity of Keifer's finest work, it's an undeniably classy show. At White Cube until 17 March (020 7930 5373); at the RA until 1 April (020 7300 8000).
