American band The Regrettes will open for Twenty One Pilots in O2 arena, Prague, on February 16th. Led by singer-songwriter Lydia Night, the Regrettes were all in their teens when they released their first music in 2016. Night formed the Regrettes with guitarist Genessa Gariano in 2015. She wound up enrolling in Los Angeles’ School of Rock program around the age of 12, which is when she first met Gariano. By that point, Night had several originals under her belt, all of which helped get the band signed to Warner.
