Hi. I started intently trying to learn to play guitar when I was 14. I'm now 52 and I'm still trying, though not with quite the same intensity I had as an adolescent.
I took lessons in accordion, piano, and even trumpet but the guitar is my instrument of choice. I still play a bit of keyboards now and then. I can also blow a blues harp adequately.
I used to only perform solo with an acoustic guitar at coffee houses and music festivals and such. These days, I still do a bit of that but my primary musical outlet currently is my rock & roll band, Axes of Ego. If anyone is interested, there are some audio and video links on the web site. We play bars and dances -- and sometimes music festivals or coffee houses. We once went fully acoustic and did a house concert, temporarily changing our name to Hatchets of Hubris for that gig.
About ten years ago, I attended a George Thorogood and the Destroyers concert and was fortunate enough to be quite close to the stage. Watching him use a slide, I thought, "Hmm... That doesn't look so hard." So, I started using a slide on some songs. I'm nowhere near as proficient as a really good slide player would be but people seem to enjoy it.
I use two guitars at gigs, a Les Paul copy in standard tuning and an old semi-acoustic Ovation (the body is all wood -- no fibreglass) in open G tuning for the slide work.
I've written a few songs that are somewhat overtly atheist but I don't think I've got any recordings of them up at this time.
