I've known this band for about 2 years, when I discovered their second album, Grand Currents.
When you know that these 3 brothers formed Hammerhedd in 2012, that the guitarist was then 9, the drummer 7 and the bassist 4, it makes you smile eventually, except when you watch their first videos. And that's when we calm down. It's enough to see them covering Sepultura covers in their garage...
Now aged 21, 19 and 16 respectively, the 3 brothers have already released 3 albums and 1 EP.
Stamped Thrash Metal on Wikipedia and other sites, Hammerhedd's music goes far beyond that. It's aggressive as Thrash, with lots of palm-muting, snarling vocals, but there are plenty of progressive moments.
One of my finest discoveries of recent years, if not THE finest.
Hammerhedd - Essence of Iron (EP) (2018)
