Via the most recent Discogs newsletter. For me, what will always be nearest and dearest to my heart is the white vinyl release of "Drastic Plastic" back in the day: https://www.discogs.com/digs/collecting/unique-vinyl-records/
My copy of Live in the Air Age has one black and one white record. I bought it upon release here in the US. As much as I like the white vinyl, it does make it difficult to see the grooves, if you want to play a single song. Although, I always listen to it straight through anyway.
From Ebay, I recently picked up a copy of 'Live in the Air Age'. It is in white vinyl. The funny thing is there are three disks with one having a whole side that is Blazing Apostles. The original U.S. release was two disks.
The white vinyl makes it all the more candy for the ear to taste.
