Hammerfall: this is a good band that you'll like if you listen to old style rock e.g. Led zeppelin. As their style is like them
Van canto : they are a German a cappella band who cover the likes of deep purple, iron maiden and Metallica. As well as different bands and even cover into the West from Lord of the Rings.
Area51: they are a Japanese metal band fronted by a female vocalist. They are kind of like evanescence in a way that some of their songs feature high notes being sung.
Arkona : is a pagan metal band from Russia, also fronted by a female who does all the vocals even the screaming parts. A good song to start with is goi, rode, goi. Which is about russ warriors shipwrecked
Five finger death punch : the lead singers voice is amazing especially when he sings, cold, far from home. I would describe them as hard rock
