Death Toll Rising are a death metal outfit from Canada who've been around for about 10 years now but didn't start releasing material until 2008. Their latest release Infection Legacy is aptly named as the album is a rather infectious one. The band's blend of Death Metal and Thrash isn't the most innovative thing around but it's well done and the production on their albums is pretty much spotless.
Check out the track 'Scorched Earth Policy':
These guys have a large amount of talent and fans of bands like Exodus, Revocation, At The Gates, Carcass should check them out. The band could definitely use your help to spread the word on them. Give them a like on facebook, and here's a link to their bandcamp.
