Wonderful mixture of 'established' and recently avant garde artists make this a must to visit - and to keep returning to. The superb Turner and Henry Moore sections by themselves draw me back each time I'm in London. Both artists are reminders that current definitions of 'mainstream' belie the fact these two both pushed the boundaries of artistic expression - and public and curatorial acceptance - for much of their careers. How exciting, then, to see the development of their respective styles displayed under one roof.
