Yeah, but it's a one time thing.
Rhapsody of Fire now has a new singer, Giacomo Voli, and the founding member Alex Staropoli.
Luca Turilli's Rhapsody is Turilli's version of Rhapsody, and he has Alessandro Conti as singer.
While maintaining the lineup and style of the band, Luca Turilli's Rhapsody will welcome aboard Fabio Lione for one last tour, before continuing with Alessandro Conti.
It's like the Helloween tour, Kai Hansen and Michael Kiske are back for a tour but when all it's said and done Deris will remain as the sole singer of the band, and Weikath / Gerstner as the two guitarists.
(I agree it's confusing, it took me a while to realize it was not a permanent thing)
