A 10th-anniversary 9xLP, 5xCD, book + DVD boxset of William Basinski's The Disintegration Loops (2002, 2003)! Includes a couple of bonus unreleased live performances.
[Edit #1, 8/9: TRL homepage actually says 9/11, or whenever it's physically ready.]
Although I never actually bought the set, I used to listen to these back when Lala existed.
"dlp 1.3" from The Disintegration Loops IV (2003)
You can download that loop & also pre-order here.
According to the Pitchfork news item, the album will be inducted into the National September 11 Memorial & Museum later this year. If you haven't heard the story already, here's a Wikipedia summary:
Loops is based on Basinski's attempts to salvage earlier recordings made on magnetic tape, by transferring them into digital format; however, the tape had physically deteriorated to the point that, as it passed by the read/write head, the ferrite detached from the plastic backing and fell off. Basinski has said that he finished the project the morning of the September 11 attacks on the World Trade Center in New York City, and sat on the roof of his apartment building in Brooklyn with friends listening to the project as the WTC towers collapsed.
I didn't realize that Basinski was born in Houston... Sorry that I don't remember a go-to article about all the info. Pitchfork linked to an earlier 9/11 article, but I'm sure there's lots of others.
[Edit #2, 8/9: my Lala post actually linked to this Stylus review - it's good.]
"dlp 4" [excerpt] from The Disintegration Loops III (2003)
Limited edition of 2,000 - apparently the only time the set will be released on vinyl, like ever. (We'll see...) Either way, seems well worth $225 to me!
But if you just wanted the standard CD's, they're $13 each over at Forced Exposure.
