What will Dave Grohl do next? The Foo Fighters frontman told Madison.com that he's planning to put together a 25-minute instrumental song, composed and played entirely by himself. "I have a studio, EastWest in L.A., where I'm going to set up an expanse of instruments -- several drum kits, a load of guitars, bass, rhythm, and lead," stated Grohl.

He continued, "I'll hit play and the clock will start ticking. I will record the first drum part, then I will run to the next drum set and play another drum part that will record over the first. Then I will do the same with all the guitars, all assigned to a different moment in the instrumental."

And given Grohl's fascination with documenting his projects in recent years, the cameras will be rolling. "The best part is we'll film everything with multiple cameras so by the end of it you will see and hear one song being played for 25 minutes, with six different Dave Grohls playing every note, on every single instrument, all the way through in one take," explained the singer.

Grohl says that thinking about the project has led to some sleepless nights as he tries to write and memorize all the instruments, but he's set to attack the project upon his return home.

The Foo frontman says he's not worried about the reaction to the project and is more interested in the challenge, adding, "If I want to write a 25-minute instrumental, write all the music, play all the instruments, film it and then, guess what, maybe never even release it? I'll do it. Just because I can."

Grohl won't be without his bandmates for too long. The band will regroup for European dates in early June. See their schedule here.
