I'll be honest. I've been listening to Eluveitie for a while now. I decided they deserved a post though, regardless of when I started listening to them. Eluveitie is a Celtic/Folk Metal band that combines some very interesting instruments into a hard and heavy hitting sound that leaves you wanting more. Many of their songs are not in English although the ones I listen to are. Eluveitie was founded in 2002 by Chrigel Glanzmann. Since then they have put out 8 albums including their demo album. They have plans to release a new album in 2018 titled Rebirth. The best way for me to describe this band is as a strange mix between Paramore and the Dropkick Murphys. If you have to time I recommend listening to the tracks I've linked below.
