In dire need of nasty, groovy riffs for lifting heavy ass weights

Love black/death/thrash/power metal. Some examples of my crack:

• Wagner Odegard Bolwark
• Bolt thrower when cannons fade toward the end of the song
• Sarcophagus by Nile toward the end of the song
• that riff in Tired and Red by Sodom after the acoustic part -The end riff of Not MY Master by Hatebreed
• End riff of Fortress of Deportation by Just Before Dawn

Thank u bros
