Earlier this month, Avicii had to pull out of the Future Music Festival due to "stomach-related illness." It looks like his April 6-7 dates in India (Mumbai and Delhi) have been canceled due to similar issues; the Sunburn Festival posted the following on their Facebook page:
‘It is with deep regret we have to inform you of the cancellation of 'Sunburn Arena Avicii India tour' in Mumbai & Delhi.
Unfortunately, Avicii has been facing health issues recently which you all might have heard of already (his recent cancellation at Future Music Festival Official in Perth & Brisbane) and has been forced to take rest until he is once again healthy to perform and travel until further notice.
We are in talks with the management to monitor his health condition and wish him a full and speedy recovery. We will work with the management to reschedule the dates later this year.
We appreciate your understanding and our thoughts and well wishes are with Avicii who is extremely disappointed to cancel his visit to India on April 6 & 7. Leave your good wishes for Tim in the comments below!’
Hopefully Avicii is OK and this isn't turning into a bigger health issues. He did just perform at Ultra Music Festival this past weekend, so who knows what the full story is.
