Query: Rata's most well known work

If you like power metal you should try this out. Rata Blanca is an excelent exponent of the genre: they can play typical power metal songs, excellent ballads, cool rock and roll themes and some great melodic instrumentals. Unfortunately this CD contains three instrumental tracks. They are really great but I wished they had included a couple of songs more. This is an album definitely worth buying.To have as a reference, Rata's style is somehow near Kamelot, Stratovarius and maybe Sonata Arctica
