An excellent band. Their music is surreal, complex and have a deep message in them. But to regular people it might look freaky. Their website is an excellent example of their surrealism. The members are Thom Yorke, Johnny Greenwood, Ed O'Brien, Colin Greenwood, and Phil Selway.

Released albums such as Pablo Honey, Kid A and Com Lag.
Oh, Radiohead is from Britain; by the way.

Radiohead is one of the greatest experimental bands of our time. Using many different instruments, and the talent of Thom Yorke, Phil Selway, Jonny Greenwood, and Colin Greenwood, Radiohead is the one of the most groundbreaking bands in the history of rock.
I shot up heroin while masturbating to "Paranoid Android". It felt really good. Radiohead!

The most amazing band of all time, and band that will become the next Beatles.

And to those that do not like Radiohead keep listening to them you will like them, they will stay with you and you will listen to them over and over. they never get old, you will take breaks but you will always comeback to them

A garbage Band that is known for their one song, “Creep.” The general Radiohead fan is a fat loser who watches Anime, hits on girls and gets rejected, has little to no friends, takes showers once a week, etc
Radiohead fans are also arrogant, insulting anyone who doesn’t like them and pretending their opinions means more than anyone who doesn’t listen to Radiohead
Person 1.) Did you hear about the Radiohead fan?

Person 2.) He’s an asshole. He was once hitting on someone’s girl.

Persona 1.) Really!? That’s fucked!

The greatest band in the universe (as stated in previous definitions) consisting of Thom Yorke (lead vocals, rhythm guitar, piano, electronics), Jonny Greenwood (lead guitar, keyboard, other instruments), Ed O'Brien (backing vocals, guitar), Phil Selway (drums, percussion), and Colin Greenwood (bass, synthesizers). Their biggest albums include (in chronological order), Pablo Honey (1993), The Bends (1995), OK Computer (1997), Kid A (2000), Amnesiac (2001), Hail To The Thief (2003), and finally, In Rainbows (2007). Radiohead is a very versatile band that has performed everything from indie to Brit-pop. And they still kick ass.

When you discover a new Radiohead song, and listen to it for so many days, you get into a state of mind where you are inexplicably happy or unexplainably mellow.
Friend one: "What's up man? You haven't been saying much. You alright?"
Afflicted: "Dude, I feel like I'm swimming over an abyss".
Friend one: "Are you Radioheaded?"
Afflicted: "Codex. Three days."
Friend one: "Nice."
