That Irish Coffee is very much like classic Purple although i was never really into them. Dust isn't too bad but not something i'd listen to a whole lotif at all :/ Here's a couple for you Doomy:
Some threads about heavy/hard rock (obscure or not) are done, do some search.
Dust are magnifique, especially on "Hard Attack"
As for Irish Coffee (the drink) > Irish Cofee (the band)
The band is kickass and totally crazy, it's just that the drink is incredible.
