Great to hear! I highly reccomend checking out more of their 80's stuff. They're just one of those bands like Pink Floyd or Black Sabbath; by that, I mean they lasted a long fucking time and went through a number of different phases. Everyone has their own preferences of what phase they favor. I love everything they've done (well...up till Sonic Nurse. Great album and return to their old school form but after that I lost hope), but my favorite Sonic Youth "phase" was this stuff. That's usually how it goes with most bands though, their earliest stuff being the best, I mean. That's how I feel, at least.
The No-Wave movement had a lot of bullshit following in the path it paved, but Swans and Sonic Youth were to that like Zeppelin and Sabbath were to Hard Rock; aka THE BEST.
Pirate Bay is like banned by my ISP. There was a huge court case here in Ireland, whereas the Countries biggest ISP wanted to ban all their customers from accessing it, so I can't even get on the home page. Total bollocks, I know.
Think it's only on a single actually, however check out this label http://www.hyperdub.net/ both the artists are on there plus loads of other good shit.
