I enjoyed a performance of Bach's Mass in B Minor last night with the added benefit afterwards, thanks to a group of fellow concertgoers on the 49 bus, of hearing about the imperfections that my cloth ears hadn't picked up.

One of their number was vigorously in favour of original instrument performance of such baroque masterpieces and if you are of the same mind you can catch one here.  Youtube tells you it's from the 2012 Proms but fails to credit the band.  The BBC archives reveal all. 

The Tommy Smith Youth Jazz Orchestra gave big band favourites a lusty outing at Summerhall at the weekend.  You might think that music is not old enough for more modern instruments to have crept in but they did have a keyboard instead of an acoustic piano. The bus man would surely have forgiven that.

Tommy's senior band, the SNJO, in their search for authenticity in their tribute to Duke Ellington go so far as to reproduce the microphone placings of the era as well as using an acoustic piano. It wasn't the one man, one mic democracy of today.
