These are my Top 10 of Finnish rock/metal bands. Apocalyptica is by far my favorite on the list.
1. Apocalyptica - They made a career playing heavy metal through their Cellos
2. Nightwish - Finnish operatic metal at it's finest
3. Children of Bodom - Some serious thrash metal, but these guys can play
4. H.I.M. - They had a trendy international single on the radio
5. Von Hertzen Brothers - Not really known on the international scene, but these Finnish progressive rockers are very talented.
6. Lordi - Lordi is to Finland as GWAR is to the US. Dress up like monsters and rock out. :)
7. Stratovarius - I just discovered them on the radio. Cool Finnish progressive metal.
8. Sonata Arctica - More progressive metal from the land of the midnight sun
9. Michael Monroe - Formerly of glam metal band Hanoi Rocks, he is probably the most well known rocker in Finland.
10. Korpiklaani - It's all about partying and having fun with Korpiklaani.
