formed a new group

While on tour to promote Consolers of the Lonely , White developed bronchitis and often lost his voice. Alison Mosshart , the frontwoman for the Kills (who was touring with the Raconteurs at the time) would often fill in as his vocal replacement. The chemistry between the two artists led them to collaborate, and in early 2009, White formed a new group called the Dead Weather . Mosshart sang, White played drums and shared vocal duties, Jack Lawrence of the Raconteurs played bass, and the Queens of the Stone Age keyboardist and guitarist Dean Fertita rounded out the four-piece. The group debuted a handful of new tracks on March 11, 2009, in Nashville from their debut album Horehound . It came out on July 13, 2009, in Europe and July 14, 2009, in North America on White’s Third Man Records label. White revealed that the White Stripes were planning to release a seventh album by the summer of 2009. On February 20, 2009 (and during the final episode of Late Night with Conan O’Brien ), the band made their first live appearance after the cancellation of the Icky Thump tour, and a documentary about their Canadian tour—titled The White Stripes: Under Great White Northern Lights —debuted later that year at the Toronto International Film Festival .
