I can see now the difference in how I view Nirvana and grunge from how you guys in the US see it. I guess for a lot of you, it really felt like "grunge" killed genres that were thriving.
Here it is different. It was a weird combination of Nirvana, Guns N Roses, Metallica (Black album), and Bon Jovi (Keep the Faith era, especially Bed of Roses!) that broke the stranglehold of pop over mainstream radio airplay and album sales. Back in the 1980s and the start of the 1990s, the only "metal/hard rock" songs that get regular airplay are the Scorpion ballads (which are videoke staples) and the occasional hairmetal pop hits. The local scene is even worse, as only one rock band is getting regular airplay then. But when the "dam" broke, Wow was it wonderful. Which is why it was not weird here back then to like Nirvana, Metallica, Guns and Roses and Skid Row at the same time
. That breakthrough led to the influx of rock and metal albums from the US and UK that we have not had access to before. For example, there was a time when I though Bleach was a follow-up to Nevermind,a nd that Lies is a GnR 1990s album.
The biggest impact, however, is in the local scene as local rock bands finally gained a foothold on the mainstream. I was in high school then, and wow, everybody is just trying to learn to play guitar, and drums. And suddenly this Catholic school I was studying in started to hold an Annual Battle of the Bands. It was so crazy, that a Woodstock-like day/night-long rock festival was one of the events during the visit of Pope John Paul II for World Youth Day.
Those were very good days.
