Rockers Kasabian are scheduled to perform at Reading and Leeds Festival this weekend, days after cancelling a gig in Belfast at the last minute.
The band also announced 12 more dates for its tour later this year.
Their headline show at Custom House Square was called off on Tuesday - moments before they were due on stage - when leader singer Tom Meighan had to be seen by a doctor due to a vomiting bug.
He was later sent to hospital to get checked over.
The band posted an apology on to their Twitter page, telling their Belfast fans: "It is with great regret, due to illness, we cannot perform at Customs House Belfast tonight."
The following day they released a statement, which read: "We were all at Custom House Square, ready to go on stage when Tom suddenly went down with severe vomiting and could hardly stand up let alone sing. He was taken to hospital, put on a drip and told to rest up.
"We had no option but to cancel and we're sorry to our fans and anyone that travelled a long way. Thanks so much for all your messages of support. Details on the rescheduled date to follow soon xx"
While the gig in Belfast has not yet been rescheduled, on Friday the band announced a number of UK and Ireland tour dates for later this year - including a show at Dublin's 3Arena on November 28.
Meanwhile, Kasabian are scheduled to perform at Reading on Friday night before making the journey on Saturday to headline Leeds.
Following the cancellation of their Belfast gig, concert goers were advised to retain their tickets until details for a rescheduled show could be worked out.
In a statement, show organisers said: "We are working on scheduling a new date for Belfast. We will communicate with all ticket buyers via Ticketmaster and on the Custom House Square social media. Tickets remain valid for the new date. We apologise for any inconvenience caused."
