Napalm Death and Dream Theater covering Metallica (notice Portnoy and Petrucci corpsing when Barney starts singing ) Words cannot describe the sheer awesomeness. Also, some wubs(ish):
Exquisite taste - haven't listened to any RMI for absolutely ages. Seen them live twice and they were excellent on both occasions (may even have gig recordings somewhere - one was the 2009 Hampshire Jam)
You are absolutely right - downloaded it off Amazon and have been listening to it this afternoon. It was released in 1989 - why has it taken me so damned long to discover this?! (I already knew about Terrorizer because of the Jesse Pintado-Napalm Death link, but never really listened to them despite being a ND fan)
I think I found them from reading about ND on Wikipedia and Terrorizer was on there or i found them via related artists on last.fm.
Other than a bit of electro swing, I usually find myself humming songs from the wonderful, emotional Steven Universe. (Actually found myself singing this in the shower.)
