A prog-rock band formed in the late 60's that had huge hits in the 70's, won a heavy metal grammy in the 80's, and still rocks and tours in the new millenium. Always known for complicated lyrics, rhythms and time signatures. Jethro Tull has mellowed over the years, but they still pluck a mean mandolin. Fronted by Ian Anderson and Martin Barre. Unfortunately this important group has been totally ignored by the brown-nosing hacks at the lame-ass "Rock and Roll Hall of Fame".
Tull (Jethro) = Jethro Tull

Hippie: "Man, Jethro Tull was bigger than the Beatles and the Stones back in the day and they're NOT in the fuckin' Rock Hall of Fame!?"

Stoner: "Yup, but who the fuck cares. The Hall of Fame is a complete sell-out, lame-ass, ass-kissing, political, bullshit institution, man."

Hippie: "Man, yer right, I guess. Hey, don't bogart that joint."

Get a Tull (Jethro) mug for your friend Sarah.
One of the most uniques rock bands ever, they started in 1969 and are still playing today.

"Jethro Tull has released over forty albums. From blues, folk rock, prog rock, and jazz influences to touches of Far Eastern sounds (to name just a few), Tull's music is not easily sorted into a defined genre." a direct quote from thier site"

Members include: Ian Anderson (guitar, vocals, guitar), Marten Barre (guitar, flute), Andrew Giddings (keyboard) and many more
"Are you going to the Jethro Tull concert?"
"That guy we learned about in science for inventing the drill?"
"You are an idiot."

(v.) The act of incorrectly assuming that a band whose name is a person's name is the name of a member of said band. This is most common by assuming that the band Jethro Tull's front man is actually named Jethro Tull, when, in reality, his name is Ian Anderson.

It is also common with the bands Gogol Bordello, Steely Dan, and Pink Floyd.
Mike: Did you see how amazingly Gogol Bordello can play his guitar?

Jeff: Dude, quit Jethro Tulling, the guy's name is Eugene Hütz, but he is most definitely amazing!

Get a Jethro Tulling mug for your mom Larisa.
Fronted by Ian Anderson (the flute-playing, codpiece-wearing badass), this band is behind the brilliance of songs such as "Aqualung" and "Locomotive Breath" as well as the concept album "Thick as a Brick."

Get the jethro tull neck gaiter and mug.
an amazing prog/folk/hard/blues rock band founded in 1968 by the most bad ass flautist ever, Ian Anderson. their first album was This Was, followed by Stand Up, Benefit, Aqualung,(their most commercial album, but quite possibly one of the best), Thick As A Brick, and countless others. The only two consistant band members since the band's inception are Martin Barre (guitarist) and Ian Anderson(singer, flautist).
to the faggot who said the beatles are heavier than Tull, listen to My God, Aqualung, Hymn 43, Cross eyed Mary, Locomotive Breath, or To Cry You A Song. all great, hard rock Tull songs.

Jethro Tull rules.

1. An amazing, english progressive rock ban led by Ian Anderson, writer, poet, flute player and singer. Jethro Tull was compared to Led Zeppelin in the 70s for creativity and intrumental ability.

2. Some dude who invented crop rotation.
1. I just got Thick As A Brick by Jethro Tull! It rules!

2. Jethro Tull invented crop rotation, whatever the hell that is.
