Hearing Appetite for the first time would probably be in the top 5 things, musically, that had the strongest impact on shaping my life. GnR pretty much changed my life in less than an hour and are still one of my favorite bands ever... I look up Van Halen related things when I want to laugh - even their hits make me cringe (You'll get some leg tonight fooor shoooore!).
Age, I think, has a lot to do with it. If I am remembering correctly, you're still pretty young, right? If you were a teenager in the 70s, the whole scene and vibe was totally different. So its not just the music, its the timing when that music comes out. I admit, hearing that line from VH NOW, makes me cringe. But I know people who were early teenagers in the late 70s who swear by the DLR era, mostly BECAUSE of DLR and his antics. It's just timing.
For me, its Guns N Roses. Specifically the Appetite-era GnR that lasted through Lies. That band was gritty, it was street, it was REAL. And all of that poured out from the music. It gave a credibility to hard rock that had become so polished at that point. I wasn't even a huge fan at the time, but I remember when I heard them in 1987, I totally understood why they got so big, so fast. And that sorta catapulted other bands to get away from the polish a bit, and get a bit tougher.
To this day, Appetite remains as one of my top albums of all time. No VH at all in my top-10. But GnR? Yeah, Appetite is just pure Aerosmith/LA Street hard rock. Damn good stuff. They were never the same after Lies. The Illusion records have their moments (Estranged, You Could Be Mine, November Rain, Don't Cry, etc.), but Appetite man, that's just another level entirely.
