Gavin and Sean of the band will be in the BBC Wales Music offices for a live webchat on Wednesday 23 March at 5pm.
If you’d like to submit a question, you can either visit the BBC Wales website, use the hashtag #blackoutbbc on twitter.
They will collate the questions, pick some of the best and put them to Gavin and Sean. So get your thinking caps on!
