I am from England, that's why I'm using a converter. Paper tag glued to the inside of the box? You'll have to explain.
EdBass, I am aware and have been since the beginning that Sunn O))) is pronounced just "Sun" and that the O))) is a graphic, we are working in TEXT here, eh?
Anyway, the "band" that exists is of the same name, Sunn O))), and I can see why lots of people don't like them. They aren't for everyone. They play what is called drone doom metal, and are at once an experimental duo and on-going collabaration project including such people as the members of Boris, Joe Preston from Melvins and Attila Csihar of black metallers Mayhem. I personally like Sunn O))) very much and see their work as an interesting experiment with sound at high volume. It'd be best to listen to something of Sunn O)))'s first, prior to you also saying "I think there's a "band" ", so you don't form an opinion on them too soon and give forth an inaccurate and misleading description of their sound. I love Sunn O))), "mundane noise" as you called it and I love traditional music, and i'll confess, without a problem, that i'm an elitist, and I certainly don't see the band as being mundane. They're extreme! Totally the opposite from mundane in the way i'm thinking. They're more about SOUND, not so much MUSIC, if you get me. So when you listen to them, don't expect to be hearing strict MUSIC. Drones aren't easy to understand, it's the effect they have on you, not about how many chords or "notes" played, it's a mystic/cosmic thing I believe, if you think about it hard enough...
And yeah, I thought Groove Tubes was a more modern manufacturer of valves. I didn't realise the grill had been painted black, I assumed it was already like that, and to be honest, I prefer black instead of grey. Good to be part of the world of Sunn!
