According Ultimate-Guitar "Out of all of the top band profiles, Sundial opted for a more dramatic path.
Probably the most interesting element is the contrasting styles of keyboardist/vocalist Anastacia Kuznetsova and singer Dimitrii “Wolf” Muratov, who have polar opposite musical deliveries that keep things interesting. While Sundial lists sympho black metal as one of their genre styles, the guitar-oriented, edgy side is often kept in check more so than a lot of black metal bands out on the scene today.
The quintet doesn’t shy from their darker nature, but it is usually balanced out by airy keyboard/piano solos that often are featured for long periods of time within each song."
