Hozier has been announced as one of the artists to open BBC Radio 1's Live Lounge month.
The Take me to Church singer said on Twitter he was "delighted to be coming back" for the month-long event, which starts on September 1.
The Live Lounge, which began in 2006 as part of Jo Whiley's show, features well-known artists performing one song of their own and one by another artist in an acoustic format.
Last year Bray musician Hozier covered the Arctic Monkey's Do I Wanna Know? and Ariana Grande's Problem.
Among the other big acts performing this year will be Sam Smith, Muse and Florence and the Machine.
Chart-toppers Jess Glynne, Ellie Goulding and Rudimental are also on the bill for the month-long event. Canadian producer The Weeknd (real name Abel Tesfaye) will close the series of live performances on September 30.
Glynne, who is tipped to top this week's UK charts with her debut album I Cry When I Laugh, will perform on September 3.
"I can't wait to perform during Radio 1's Live Lounge month. It's always so much fun and such a great celebration of live music. Woooohooooo. See you soon," she tweeted.
Other acts on the line-up include FKA Twigs, The Libertines, Disclosure, Naughty Boy, Demi Lovato and Selena Gomez.
"I can't wait to return to the UK and perform my new music for the first time during Radio 1's Live Lounge month," said Lovato.
The weekday Live Lounge sessions will be hosted by Clara Amfo from Monday to Friday, between 10am and 1pm, while Alice Levine will host the weekend shows on her 1-4pm Radio 1 slot.
"Since starting this slot on Radio 1, the Live Lounge month is something that I've been looking forward to," said Amfo.
"There's a really strong mix of artists coming in and I can't wait to enjoy their performances alongside the listeners."
