Aerosmith concluded a tumultuous year by announcing that its front man, Steven Tyler, had entered a rehabilitation facility to treat an addiction to prescription painkillers, Rolling Stone reported. In a statement, Mr. Tyler told Rolling Stone, “With the help of my family and team of medical professionals I am taking responsibility for the management of my pain and am eager to be back on the stage and in the recording studio with my band mates.” Over the summer, Aerosmith canceled an injury-plagued tour whose final show occurred on Aug. 5 in Sturgis, S.D., where Mr. Tyler, 61, fell from a stage. In November, the Aerosmith guitarist Joe Perry said that Mr. Tyler had quit the band, then reunited with him days later at a concert in New York. In his statement to Rolling Stone, Mr. Tyler denied that he planned to take a hiatus from the band. “ I will enthusiastically be writing, recording and performing with Aerosmith as soon as things are handled,” he said.
