Here is just a taste of Brahms' well known "Double Concerto." Technically, this is his "Concerto for Violin, Cello, and Orchestra". This recording features Truls Mørk, cello; Lisa Batiashvili, violin; Sir Simon Rattle, conductor of the Berlin Philharmonic.
Students: How many movements are in this work, and about how long is it in full?
If you have time, I suggest you listen to recordings of it in full length!
