I grew up in my hippie parents house listening to the Animals, Eagles, Kansas, Fleetwood Mac.. amazing pop music at the time but now we call it "classic rock"
As soon as I could choose for myself, it was the '80s and hair bands and pop metal were all the scene. I played bass in a couple bands in high school and we covered Metallica too! And Van Halen and a bunch of other terrible hair bands.
When I got to college I pretty much stopped playing bass. My bass had been stolen and I was inspired by my roommate who would sit around for hours finger-picking his acoustic; he taught me a few chords. For about 10 years I played mostly acoustic guitar. Some of any blues, pop or rock genre songs, and lots of "classic rock".
Then 2 years ago, I got divorced and had lots of time on my hands. She took her basses with her and I immediately went to buy a replacement... quite out of spite, I think.
This will sound crazy.. but at 35 or so, this is when I discovered Jaco and Stanley Clarke. And Prog/Fusion Jazz. I had my mind blown. So at this point I dove into jazz fusion and some of the standards too.
Now I play all the time, more on bass and guitar both than I ever have. I'm in a cover band again for the first time in 20 years, and we're writing songs too. We cover ... the same kind of classic rock tunes. But the basslines I write for originals come from all of that - metal, rock, hair bands, jazz, fusion, and classic rock.
