Music at Work: Shostakovich

Classical music is always a good background at work if I need to shut off from office noise around me. Structured music like for example from Johann Sebastian Bach helps thinking in an concentrated way. Recently I purchased Shostakovich: Cello Concerto No1, Op107; Violin Concerto No1 (revised), Op99. This music is different from the classical music I usually listen to. Shostakovich wrote the Cello Concerto No. 1 in E Flat Major, Opus 107 in 1959 (see also the article on Wikipedia). At the first I was listening to the recording I thought I might regret getting the CD. But then I got to the Cello Concerto which turned out to be a fascinating piece of music.
