I've recently left a band that did 40 or so shows a year to do around one a month. It was becoming too invasive into my family time, plus Mrs ead is getting over cancer atm so I need to be around a lot more. Something like would be fine for me.
Aside from the 'gigging' band I also belong to an 3-piece originals band. Definitely hobby/social aspect to it. A couple of rehearsals a month and we'll do a few gigs when we feel like it, although of course venues for original music are getting hard to find around here.
