LOK was a Swedish hardcore/rock band that existed a few years in the late 90's and the beginning of 2000 before they broke up. Lok had a decent mainstream career in Sweden with a couple of well selling singles and albums, but sadly they never really reached out to Europe and the US, most likely because all their lyrics are in Swedish. Lok's sound can be described as heavy, down tuned, hardcore mixed up with plain old rock n roll, catchy hooks, a touch of Rapcore which is harsh rap/screaming vocals.
