Haha, I get what you are saying. A while back I did an old bass-playing brother a favor when he was hooked up with an original act that had just released their first album. Struck me as really odd at first because this cat was someone I knew from the trenches of the Metal club circuit in the '80's and would have never thought he'd get involved in this type of project: it was a power pop thing fronted by a female singer/songwriter type - more Alanis Morrissette than Alice In Chains if you know what I mean. Anyway, the record was out and it was time to play a bunch of support gigs, but they only had one guitar player and couldn't pull off the material, as studio guys had done a lot of overdubs and all the solos, so he asked me to step in as a favor for the gigs. Man, what an eye opener. Learning a full set of that style of music challenged me in a way that in the end was a great experience which taught me a lot and gave me a better appreciation for what people in these other genres are up to. Challening musically? Hell no. But challenging as an exercise in learning and growth, for sure. But, to fill out the sets we also worked in a bunch of covers and I found that part really distasteful - god I hate playing covers.
ty, wood plank floored honky tonk at 15. Back then i could play and sing effortlessly.
