A few days ago I saw the Cleveland Orchestra perform Dvořák's Sixth, then they accompanied the one and only Yo-yo Ma in Elgar's Cello Concerto. The place was absolutely packed out, at least a few thousand people were there. I was there last year to see them perfrom Stravinsky's The Rite of Spring with the dancers, and that was nowhere near as packed.
Anyway. I'm partial to Elgar's Cello Concerto. The opening cadenza is good, but the whole shebang is thirty minutes long and it's not... really that memorable otherwise.
Dvořák's Sixth though... the first movement is one of my favorite one of his compositions.
Skip to 11:30 in that video, the end of the first movement. Just listen to the trumpet and trombones echoing each other, it's such a great moment in music.
A pretty obscure work I was shown: a piece for pipe organ called Tu Es Petrus. I love the sound of it.
And an organ piece I will love forever. Healey Willan: Passacaglia, Fugue, and Introduction.
I love this piece probably more than any other single solo work out there. Any organ composition that features the lower sounds this heavily has to be great. The passacaglia starting around 4:30 is my favorite. That gradual build, the repeating theme from the pedal tones, the wide array of melodies that overlay the bass theme, the ranges of sounds the piece calls for (namely the harp, tuba and oboe stops), the great sound of the G-flat key... Love everything about this piece, but that climax in the passacaglia at around 10:30 where there are slight variations in the pedal theme... I don't know if I'd say my favorite bass sound in all of music, but it's up there.
