Florence + the Machine's Florence Welch does not want to damage her gorgeous voice, and thus the band has cancelled the final two dates on their current European tour. Thursday's gig at the Benicassim festival in Benicassim, Spain and this weekend's performance at the Optimus Alive gathering in Lisbon, Portugal have both been nixed due to her unidentified vocal issues.

"Yes its true ... it finally happened, I've lost my voice," she started in a series of tweets on the matter posted on her personal Twitter account. "I've sustained a vocal injury and been told I cannot sing for a week," she added in another. "Seriously I felt something snap, it was very frightening."

Another Twitter post apologized for missing the dates: "I'm so sorry to all the fans, I was desperate to still perform, but was told without question not to, so as not to do permanent damage," she wrote.

Despite the numerous tweets on the issue, Welch did not reveal the exact nature of her vocal injury. Regardless, Florence + the Machine aren't scheduled to resume touring until a July 20 gig in Burnaby, British Columbia, giving the singer plenty of time to rest her voice. The band currently has shows scheduled on-and-off through a Dec. 2 show in Frankfurt, Germany.
