Grundleburst 

An awesome band. They rose to fame with they're number 1 hit song, "2 Cool 4 School". Their songs are generally recorded in one take around a single mic, and often improvised (though sometimes based off of snippets of magnetic poetry. The members are as follows:

Mick Furgn: Vocals
Nick Schweinstegger: Guitar, backup vocals
Max Sven III: Kazoo

Their first album, released in 2006, was called Imagine Shlock, and was recorded on two non-consecutive afternoons.

I just listened to Grundleburst's debut album Imagine Shlock and it was so good.
