I have Over the Edge Vol 4 on cassette – the CD has been very elusive to me for some time now and it’s not on any of the streaming services.
While I generally avoid buying music physically these days I always try to seek out Negativland’s stuff because they always throw in so much weird extra stuff with the physical packaging (let’s not forget after Don Joyce died, his ashes were included with their subsequent album release).
Sadly, over the years I’ve lost most of the little trinkets and baubles that had been included with the stuff of theirs that I’ve bought.
