Mr McFall's Chamber
 

As well as lots of Piazzolla tangos, this Scottish ensemble play excellent arrangements of King Crimson, Frank Zappa and others. The ensemble contain a number of musicians from the excellent Scottish Chamber Orchestra and their music is worth investigating by anyone, especially those with "classical" leanings. I heard them do a gig last night in Edinburgh and the quality of the arrangements and playing was first class. More info and sound clips at http://www.mcfalls.co.uk/
