Classical Recommendations

Ralph Vaughan Williams: Symphony #5, Fantasia On A Theme By Thomas Tallis, The Lark Ascending

Most Mahler Symphonies.  Some one has recommended the Eighth.  I would for the Second, the Ressurection.

 Shostakovich symphonies in particular 5 and 11

Generally speaking, classical music wasn’t composed to “rock your socks off”.  It wouldn’t be until the Romantic era of classical music that you get the dynamics that you’re looking for; however, it is a good place to start your interest into classical music in general.  You’re basically looking at pieces by Beethoven, Brahms, Tchaikovsky, Liszt, (and Rachmaninov).  For just drama, Tchaikovsky’s Piano Concerto No. 1 is hard to beat, and  would have ended the Cold War in 1958 with Van Cliburn, had it been allowed.  

Also Sprach Zarathustra 

Holst - the Planets - esp Mars

Mahler symphonies - there are always such movements - in the early days of stereo a common rallying cry was "Mahler was made for hi-fi".

Verdi Requiem - the Dies Irae.

The last movement of Beethoven's 9th.  Berlioz Symphonie Fantastique.

If I might change the mood, the wonder of "classical" music is that every feeling and emotion can be found.  For me the single most profound 15 minutes in music is the Molto Adagio - Heiliger dankgesang of Beethoven's op. 132 quartet in A minor.  Every emotion is explored in this movement, melancholy, joy, hope, despair, thankfulness and anger.  The Alban Berg recording on Qobuz is outstanding, do listen when feeling reflective!

The greatest music can blow you away even when quiet.
