If you don't know it, Arte is a a European public service channel and Arte Concert is their live music. The live concert performances are top quality and it's all free to watch, with *no ads* (thanks EU!).
This evening I've been watching a jazz concert by Hiromi's Sonicwonder. Earlier in the week I watched Moderat live at the Grand Palais in Paris. I've discovered fantastic African blues musician Fatoumata Diawara and Cuban funk musician Cimafunk and singer song-writer Asaf Avidan. There's everything from metal to electronic to jazz to classical.
While a lot of the internet has been turning to ad-filled spyware goop, Arte Concert is a wonderful exception.
This is me feeling grateful.
