Ah, Portishead. I miss them. Get their other album as well, Cobra. I forget which is the one I like better, but I'm pretty sure it's the 2nd one. Either way, one is infinitely superior to the other, I think, but both are unique and cool. Yes, it would be trip-hop, though it's not exactly like some of the other bands you'll find that call themselves that (
Moloko,
Morcheeba,
Thievery Corporation --
2). It's a little more jazzy and stuff, a little darker, which I think is what I like about it so much.
But yeah, I'd be curious to hear more of what you think of their other album. I really need to get those on my MP3 player again.
EDIT - Amazingly, they have a third album out! It's called... uh,
Third. Their 2nd was self-titled. Apparently it's a little different from their past stuff, and less trip-hoppy, which I guess could be bad... we'll have to see. It's the first thing they've done in... what, 10 years? These people aren't exactly what you'd call "active" under the banner of this group.
