I went to see Testing the Echo at the Playhouse last night.
It certainly did that - my brain felt so tested it has been protesting ever since.
There are some particularly pertinent points made in this look at Britishness and the country's test for would-be "citizens" - and some frighteningly topical lines, given this month's debate over Sharia law.
Following last week's superb Metamorphosis, the Playhouse has got its 2008 programme off to a challenging and flying start.
