U.S.V. did a 7" on Havoc and the 'Chokeslammed Back To Life' LP on Deranged. Both aren't that difficult to get. The recordings aren't that powerful as on their their later releases but worth checking out anyway.
Don't know anything about The Krammies. They're not a bad listen but nothing special.
This 7" was released in 1997 on Punk House.
1. Get Real Drugs
