[UPDATE: 04/16/2014 10:38 AM]:
After a couple days of rumor and speculation, AC/DC has confirmed via its Facebook page that guitarist and co-founder Malcolm Young "is taking a break from the band due to ill health. Malcolm would like to thank the group's diehard legions of fans worldwide for their never-ending love and support. In light of this news, AC/DC asks that Malcolm and his family's privacy be respected during this time. The band will continue to make music."
Contradictory reports continue to swirl around AC/DC and the future of the band.
After initial rumors that the group was about to retire due to health of guitarist Malcolm Young, Australian music blogger Darryl Mason reports that Young suffered a severe stroke earlier this year that left him with a brain clot and is in need of full-time care. Mason writes that AC/DC reconvened in April for rehearsals but "Malcolm discovered he couldn't play" and that "friends and family of band members believe the decision was made last week to call it quits."
Meanwhile, Mark Gable of the Australian band the Choirboys and a friend of Young and his brother Angus Young, told a radio interviewer that Young "is unable to perform anymore. It's not just that he is unwell, it's that it is quite serious...He definitely won't be able to perform live. He will probably not be able to record." Gable did, however, say that AC/DC was not calling it quits and floated the possibility that Stevie Young -- Angus and Malcolm's nephew who has filled in for Malcolm in the past -- could step into the breach this time.
AC/DC's management and record company, Columbia, have chosen not to comment on the reports, while other anonymous insiders have said they're false -- at least in regards to the band retiring. The group is said to have booked six weeks of studio time starting May 1 in Vancouver, where AC/DC recorded 2008's "Black Ice." Frontman Brian Johnson -- who has made comments about one of the band members being in bad health in the recent past -- has also said that the group is planning a 40-date 40th anniversary tour this year.
