Auri is a trio consisting of Tuomas Holopainen (keyboards, songwriting), Troy Donockley (various winds, guitar, vocals), and Johanna Kurkela (vocals). The first two are bandmates in the Finnish symphonic metal band Nightwish, Johanna is Tuomas' spouse and has her own career as a singer going. For their upcoming third album, Auri have added a drummer and, no surprise, it is Nightwish drummer Kai Hahto. So half of Nightwish is now in Auri as well. With Nightwish on hiatus for this year, they are also able to do a fairly extensive tour, something Auri has not always been able to do given all members have other musical lives.
Trivia: The name is taken from a character in Patrick Rothfuss' Kingkiller Chronicles, a favourite of Tuomas. He has also written songs based on the books for both Nightwish and Auri.
