Those 2 songs were the obvious choices for us Americans. Here in Orlando, when the album was first released, they started playing “Betrayer” and “Extreme Aggressions” on WUCF’s Midnight Metal. If you wanted metal, that is what you listened to. The only problem was that Midnight Metal was only on the air for 6 hours, and it started at midnight (Sunday) and ended at 6 a.m. on Sunday morning. It was awesome because they had a rule to play no mainstream music and their saying was “WUCF’s Midnight Metal, where we play none of the hits, all of the time.” Back then…in the late 1980’s, with no internet…. you were extremely happy to have Midnight Metal.
Shortly after I heard Betrayer on Midnight Metal, I bought the album. A week after that, we could then find Kreator’s earlier releases as they were almost non-existent at the local record store before Extreme Aggression was released. So I then was lucky enough to get Endless Pain and the others.
