All I can say is all of them, which doesn't help you much, I know.
But if compiling for a friend (I don't want to get 'shot' by other fans); I'd lean towards their later albums 'Origin of Sym'; 'Absolution' and 'Black holes etc' plus 'Plug in baby' and 'Unintended' from earlier albums.
Thickko me; I've just realised your post was made some 6 months ago.
I didn't check its date; as like with my discussions on other subjects, not many make the effort to reply.
I was trawling thru' Amazon's 'movers and shakers chart' and came across this.
Of course if you are a fan yourself, you'll know of HAARP now. If not, it's a CD plus a DVD of their Wembley concert from last June.
Almost certainly too late; but that's the answer!
Cheers (I hope your friend is/was happy, but if you're still waiting, just buy HAARP!)

CATS WALLER, you seem to be like a pretty die-hard Muse fan also...I'm curious, what was the first Muse song you ever heard?
