Thick As A Brick
The definition of "masterpiece." Jethro Tull's definitive progressive rock concept album. The whole album is one 45-minute long song. The lyrics appear to have some deep hidden meaning on the surface, but delving deeper, they are actually satirical, done with Monty-Python style humor. The music is complex, seemless, moving, and is undefinable to just one genre.
The mainstream can go listen to their H.I.M., 50 Cent, beyonce, or my chemical romance. That's their choice (a choice that's "thick as a brick" indeed). I'll go listen to some REAL music... (puts on some Jethro Tull)
Thick as multiple bricks
When your more than just thick but quite thicker than a brick one could say that your as thick a multiple bricks
