AND THEN THE LIVESTREAM TURNED ITSELF INSIDE OUT: Yo La Tengo is on WFMU today from 9 a.m. -- live from Germany, for crying out loud -- playing requests in exchange for pledges. Yes, they do this annually. Yes, you will be subjected to pledge solicitations and related patter between sets. Yes, if you are at liberty, you should totally be streaming this. ...and yes, if you're rolling in dough, you should totally send them some.
ETA: You may need WinAmp for the livestream, if you don't have iTunes on your comp. I did. Windows Media Player didn't want to play it. WinAmp was a quick install, but there were a ton of seeming bloatware and optional "services" to de-select. So, watch for that.
