Sinéad O'Connor's cancels, Bjork cancels

Bjork has been forced to cancel two shows after discovering she has a nodule in her throat. The Icelandic singer, who is touring her eighth studio album 'Biophilia', had been in residence at the Buenos Aires Centro de Exposiciones in Argentina since April 6, but has been forced to shelve the final two shows of the run after the diagnosis. Sinéad O'Connor has also been forced to cancel her upcoming U.S. tour due to her battles with bipolar disorder. In a public statement O'Connor said she suffered a "breakdown between December and March," and she had been advised by her doctors to cancel her tour. The outing was in support of her recently released album, “How About I Be Me (And You Be You)?”
