Bands that were good and got better.
 

Nick Cave & The Bad Seeds (later stuff is better than early stuff and also better than The Birthday Party)
Nick Lowe (last two albums have been his best)
Captain Beefheart (last two albums were his best)

Shora
why?

Yeah, I think Beefheart got better as well.
Venetian Snares keeps getting better.
Brainiac
XBXRX
Scissor Girls
Slowdive
Secret Chiefs 3

I dunno, probably a lot, I just woke up and can't think.

I was about to say "brainiac", but there are so many great songs in wach album it's hard to decide which one is better(not just production-wise)..and electro shock for president, not sure it's theire best output...maaaah!
oh well, they're great either the case.

Discounting that EP, I think each full length was better than the one before it at least.

big black. i like atomizer better than SAF but they both are better than the lungs ep and their other early material
the clash for a bit, then got a bit worse.
THE BEATLES
the boredoms
lightning bolt

Radiohead.

Fugazi.

I'd say Zu, even.

sonic youth?
weak first ep, then weaker confusion is sex, than good bad moon rising and 'katharsis' with evol ;)

I really really need to check out Atomizer. I can't find it anywhere though. :(

*coughs*

Haha confusion is sex is probably their best album.

the 1st ep is great. and CIS and BMR are whats known as "Mary Poppins" albums

ie-practiclly perfect in every way

Even though it's a good album, everyone here sucks the dick of BMR.

Also ATL. That one's another one thats overrated by fans.

I don't suck BMR's dick.

I do suck ATL's dick though.

Well, actually, I just lick its taint and milk its prostate.

John Coltrane just got better and better. His first bebop recordings were pretty cool but his music just evolved into this powerful beast. His compositions got more and more freeform and complex.

Time Of Orchids. Their first records were alright but not very matured. Then starting from Sarcast While, their sound just became more refined and I guess matured hah.

JANDEK.

I've never thought of Jandek to be good and got better, he's always just had different phases of styles
