Here's 2 videos of my favourite classical orchestral concerto.
Original composition of Antonin Dvorak.
Symphony No.9 "From The New World" 1st movement "Adagio - Allergo molto
Symphony No.9 "From The New World" 4th movement "Allegro con fuoco"
If you dunno, the orchestra here is conducted by one of the greatest conductors of the 20th century, Herbert von Karajan.
