Oh! Did I say bass saxophone concerto? What I really meant was Bass Saxophones Concerto. Actually many bass saxophones, as in FOUR bass saxophones.
An amazing presentation clip about Xavier Carbonell's Lalibela, a concerto for 4 bass saxophones and symphony orchestra.
Performed by the Sigma Project Quartet. The presentation is in Spanish, but even if you don't understand the language, the visuals and sounds are worth a watch. What a sight.
