Grohl spent four years as the drummer for Nirvana. Unbeknownst to most of Nirvana's fanbase, Grohl had gradually written a stockpile of songs that he had largely held back from the band for fear of ruining their chemistry. (Grohl has noted in several interviews that he was well aware of the infamous drummer joke: "Q: What did the drummer say just before he got fired? / A: 'Hey, guys, let's try one of my songs!'") Instead, Grohl occasionally booked studio time to record demos, and even issued a cassette of some of those songs called Pocketwatch under the pseudonym Late! in 1992.
The release of the band's first ever live/acoustic CD, Skin and Bones was released on November 7th, featuring fifteen performances captured over a three night stand in Los Angeles. The DVD release is set for November 21st.
