From All Songs Considered's Tiny Desk Concerts - the in-office concert series. Loads of concerts each a bit shy of 20 minutes long. Here is Reggie Watts (who grew up a few hundred feet from where I did in Great Falls, Montana)
The BBC4 program When Björk met Attenborough … you may want to look at it in the near future as the BBC sometimes has youtube posts taken down. Probably better than anything on tv you'd spend an hour watching.
The focus is her Biophilia project - an ambitious set of works with music inspired by nature and expressed through conventional music, nature and technology. It is also tied into her project to create a more intuitive music that allows non-musicians to realize some creativity. Biophilia was released as an album and also as an iPad app. I've spent a fair amount of time in the app - it breaks some new ground, but much remains to be done .. particularly on the creative side. A good first attempt! I hope she and others continue along these lines with the richer ideas that will emerge.
