Bands that have never failed you.

[Anacortian]

For me, it's the Offspring. Some may say they have fallen, but I think they have only grown to sound more like themselves. They started as good but generic punk, and they grew to something that sounds like nothing else.

While I would not say that each album has gotten progressively better, I will say that each album has been enjoyable.

 

[theguitarhero6]

Municipal Waste
Great Party/Crossover/Thrash from all 4 albums.

 

[Clockwork Scarecrow.]

Gorillaz.

 

[Artina89]

For me it's Voltaire. So far I have not wanted to skip a single track of his and I have enjoyed all his albums. I was also going to mention Queen but then I remembered the "Hot space" album. All I can say is, "ugh...."

 

[Cuddly Knife]

Gojira
Deathcab for Cutie
Machine Head
Incubus

 

[Ekonk]

Daft Punk. NEVAR HAVE THEY EVAR FAILED ME.

I'd also say the White Stripes, but since they've broken up they have failed me.

 

[Eogris]

mastodon

Edit: Dillinger escape plan as well

 

[wickermole]

let

 

[Duffeknol]

Devin Townsend. Everything the man has done, metal, ambient, rock, noise, it's all good. All of it.

 

[AlexLoxate]

Red Hot Chili Peppers... timeless

 

[EatPieYes]

I've yet to hear a bad album, atleast studio album, by King Crimson.

 

[Restoshamankk]

Megadeth, I don't care what you say about Risk!

 

[Saltyk]

Gotta say Disturbed. Haven't heard the new one, yet, but all of their albums rock. Easily one of the best bands out there, in my opinion.

 

[ciancon]

Arcade Fire. A band of consistant awesomeness!

 

[Amnesiac Pigeon]

Radiohead, Tool and Puscifer are bands that I consider to not have released a dud album

 

[JamesBr]

Opeth
Machinae Supremacy
Infected Mushroom

And if Dethklok ever releases a third album, they'd be on this list also.

 

[CrazyGirl17]

Gorillaz, for the most part, as well as Linkin Park (Yeah, I know, but I'm partial to both their new and old music).

 

[Cgull]

Off the top of my head;

Stereophonics
Reel Big Fish
Electric Six
Skindred

 

[the Dept of Science]

Radiohead
Nothing but pure gold

Even Pablo Honey?

If you discount their last album, which was a bastardised version of the band, then the Velvet Underground.
Their first record, the Velvet Underground and Nico, is easily one of the most influential albums in history, inventing pretty much all the tropes that went on to become not only punk and alternative rock (but also massively influential on heavy metal, indie pop and singer-songwriters)
Their second album distilled out all the poppier aspects of the first album, and resulted in something sludgier and crazier than anything that I have ever listened to (and this is in the 60s)
Their third album went in completely the opposite direction, dropping most of the noisier aspects of the first album and putting out something that feels very personal and intimate
Their forth album they decided to do a classic pop album, and they fuckin' nailed that as well
They also have some great live albums and a rarities comp

Others:
The Flaming Lips
Nick Cave and the Bad Seeds
Tom Waits
Frank Zappa
The National
Los Campesinos!
LCD Soundsystem
the Arcade Fire

 

[Sparrow]

Kings of Leon and Biffy Clyro instantly pop to mind.
