Joining Jools for the fourth show of this series are Mumford & Sons, Joanna Newsom, Hole, Iggy Pop, Ozzy Osbourne and Angelique Kidjo.
Joining Jools are London-based Mumford & Sons, who have been gradually accumulating fans and selling lots of copies of their debut album Sigh No More, from which they perform a few numbers.
Harpist Joanna Newsom returns to the studio to play a couple of songs from her recent acclaimed Have One On Me triple album; and Courtney Love and Hole make a welcome return to the studio for the first time since 1998 to perform tracks from their new album Nobody's Daughter.
Iggy Pop pops in to discuss the reissue of his incendiary classic album Raw Power, and Ozzy Osbourne is on hand to chat about his career. Finally, from Benin, West Africa, Angelique Kidjo performs numbers from her new album Oyo, which pays tribute to the music that inspired Angelique's childhood, such as classic songs by Curtis Mayfield and James Brown.
