I just recently got an HDTV so I've never had this channel called Palladia until I discovered it a few weeks ago. It's basically live music, all the time. Shows like Unplugged and Storytellers, along with hourlong cuts of bands on tour, in nice, widescreen, HD glory.
So far we've watched AC/DC, Pearl Jam, Snoop Dogg, The Police(!), KT Tunstall, Sheryl Crow, Tom Petty, Bon Jovi (that one proved popular at the housewarming), Coldplay (meh), The Who, Genesis, Lenny Kravitz, Nine Inch Nails (Live Beside you in Time), and the Bangles.
That's right, the Bangles, as in Walk like an Egyptian. And I've only had the channel a month!
Just finishing up an hourlong set of the Chili Peppers (great solo in the middle by Flea). Someone even told me that the channel is run by MTV, which really made me laugh because there's music on it.
