Avatar is a such a great band worth checking out if you're not familiar with their work. They've been around since the 2000's but didn't gain attention in the US until the mid 2010's with their Feathers and Flesh album which took the band in a new direction. Their earlier work was strictly heavy with harsh vocals, Feathers and Flesh incorporated a more melodic sound yet loosely retaining a heavy sound. The vocalist can change his voice quicker than the flick of a light switch, he's impressive.
From their Black Waltz album which is arguably their best album you can feel the singer's emotion in this one and this is one of the best portrayals of what Avatar used to be,
This is my favorite Avatar tune also from the Black Waltz album if you didn't know this was a Swedish metal band with the riffs you'd think it was a Southern Metal band.
This is where the band took a huge shift with their sound and in my opinion it was for the better and demonstrates how versatile Jonas can be and that he isn't a one trick pony that can scream.
This one has hints of AC/DC to it and demonstrates Jonas' wide vocal range.
Lastly here we are in the present I feel these two tracks are perfect representations of where Avatar has been and where they're going.
