3 December 1935 saw the debut of a new orchestra in Glasgow: the BBC Scottish Orchestra. This week, as the BBC Scottish Symphony Orchestra, they celebrate their 75th birthday. Katie Derham celebrates in Afternoon on 3 with a selection of exciting new recordings and and archive highlights from the orchestra's history. The week features recordings with most of the orchestra's Principal Conductors - from their founder Ian Whyte to Donald Runnicles, who's been in the post just over a year - and some of their most famous Assistant Conductors, including Simon Rattle! There's also Scottish music every day, and we visit all five cities where the orchestra perform regularly - Aberdeen, Edinburgh, Glasgow, Inverness and Perth - as well as Munich and Vienna on their recent acclaimed tour of central Europe. Today's programme features Andrew Manze's debut as Associate Guest Conductor of the BBC SSO . The concert starts with a brand-new bowl of sweet cherries from Sally Beamish to contrast with Brahms's Fourth Symphony - which, Brahms said, 'takes after the climate in these parts: the cherries don't grow ripe and sweet here!'
