Sir Simon Rattle loves Bruckner’s Fourth Symphony, and on this new recording from LSO Live, he conducts the work in all its splendor. Rattle is aware, too, that Bruckner’s inspiration burned so brightly that he ended up with more ideas than he could actually use. “There is much wonderful music which remains almost entirely unplayed,” he says. On this album, Rattle steps inside Bruckner’s workshop, bringing to light some of the music that didn’t make the final cut. This edition of the symphony and its discarded Scherzo and Finale by Benjamin-Gunnar Cohrs was published in 2021. The world-premiere performance with the London Symphony Orchestra gives us a glimpse into the composer’s untold musical thoughts.
