Same here//// when I was 13-15, I had a good friend from a rich parent who just loved to please his son. We loved live music, what can I say. Soooo, once a month or so his dad would drive us to Hannover or other cities for some awesome concerts. Back then in Germany it was no problem at all getting into concerts at a young age.
Santana, Zappa, Wishbone Ash, Rory Gallagher, Jane, Eloy, etc, etc. Probably have seen over 100 bands before I was even 18 years old.
Also, hung out with the Scorpions when I was just 14 , being on the stage playing air guitar. (Rudolf must have gotten a kick out of that)
When I moved to Hannover for College, things got even easier.
We're talking mid-70's to mid-80's here, when the music scene was fantastic. I remember my first concerts being Sweet, Slade (great), Middle of the road, Colloseum, Manfred Mann's Earthband, all before I turned 14. Those were great times.
I also remember vividly some great light shows, especially those with psychedelic rotating lights.
Well, got myself a Mania DC3 with oil wheels, and reproduce that myself in my room now. Man, it's groovy....
