I'm 62. It's tempting to give a very long answer. I'll try and be concise.
From my teens I found live music awesome. Until my early 20s I was just a ragged guitar basher, then I discovered bass and found I could play it reasonably. I got into a covers band, followed by two originals bands.
Then I got married and for about 22 years did no more than the odd noodle every year or two.
As divorce became inevitable I started playing for my own pleasure, put in liafs of effort, then signed up for a "weekend warrior" scheme. I discovered thst I was actually a reasonably good player with a good ear.
I also rediscovered how making music was fundamental to who I am.
From that scheme arose a band. We only gigged twice, then covid and the divorce finished, and I came back to Wales to look after my dad just over four years ago.
Since then... I joined two bands, one, three piece blues, I am still in. My first gig with them I met a lady who is now my partner and as obsessed with live mumusic me!
The other band, I left as try just weren't serious about gigging - three in two years. I founded another band, five of us playing classic/ heavy rock we all love.
My dad passed last year. With the BL of the blues band finding success with a young indie band, and all if us in the other band having multiple bands I haven't had as many gigs as I want. Iwas maling up dome of the slack with dep gigs and open mic/jam nights.
Then a friend has decided to resurrect his old band with new members to record a new album, and I've joined up to what is a one album and a few gigs project.
Then a band I know have asked me to take on bass as their bassist has moved to keyboards. They are a really good old-style rock band playing about 30% CCR and a great bunch.
So my answer:
It keeps me sane and happy.
My partner is super supportive.
All the bands have great musicians.
who are also friends.
But most of all I love jamming, improvising and learning new material.
