Let's start with something out of the mainstream ...

This event (http://ticketing.southbankcentre.co.uk/find/music/classical/tickets/wolfe-adventures-in-sound-68645) is part of "Ether, Southbank Centre's festival of innovation, art, technology and cross-arts experimentation". It may not be everyone's cup of tea but check the samples and see what you think.
Personally I can't resist the idea of a bagpipe group called the "Red Hot Chilli Pipers"; but that may be just my Scottish ancestry speaking.
From prior experience of this type of event, sound levels tend to be quite high - I've booked my own ticket in the top row of the hall.
