Hotting up - Elgar at the Proms

First Night of the BBC Proms Friday : Elgar The Kingdom which i guessed thru mysterious powers (more here).  An ideal extravaganza with which to start the summer. Even the weather report suggests a surge in the temperature. Elgar  took to technological change with zest, making numerous studio recordings and taking part in films. No regressive fuddy duddy he ! Below, the composer conducts the Prelude to the Kingdom. There aren't any photos I can find  showing him directing The Kingdom, so I've used one where he conducts the Dream of Gerontius.  You can imagine the premiere in 1906.  Lots more on this site about Elgar, composer recordings etc and The Apostles, a work closely connected to The Kingdom (read more here)
