TED has some incredible offerings these days. Here is one that about knocked me out of my chair. Turn up your computer sound and sit back for 20 minutes. Here's the description from TED.

Gustavo Dudamel and the young members of the orchestra, many born into poverty, had had their lives transformed by a national music teaching program built by TED Prize Winner Jose Antonio Abreu. The Teresa Carreño Youth Orchestra contains the best high school musicians from Venezuela's life-changing music program, El Sistema. Led here by Gustavo Dudamel, they play Shostakovich's Symphony No. 10, 2nd movement, and Arturo Márquez' Danzón No. 2.
