Bowie was awarded the Grammy Lifetime Achievement Award on 8 February 2006. In April, he announced, "I'm taking a year off—no touring, no albums." He made a surprise guest appearance at David Gilmour's 29 May concert at the Royal Albert Hall in London. The event was recorded, and a selection of songs on which he had contributed joint vocals were subsequently released. He performed again in November, alongside Alicia Keys, at the Black Ball, a benefit event for Keep a Child Alive at the Hammerstein Ballroom in New York. The performance marked the last time Bowie performed his music on stage.
