Age 10: learned a smattering of recorder; soon abandoned the instrument. Ehhh, that's most kids, right?
Age 13: started playing piano and composing/songwriting. Progress was quite slow at first due to my refusal to learn written music.
Age 14: started self-training classical vocal techniques. I wanted a meaty challenge.
Age 17-19: recorded various classical/operatic music in a studio; never released said music due to flawed vocal technique issues.
Late 2012: abruptly stopped singing due to increasing hyperacusis. This is still an issue and possible always will be.
2012-2017: occasional composing, very little singing. Instrumental concept album sketched out for a novel project.
Late 2017: unexpected bursts of creativity persuaded me to get back into singing on a limited basis.
Mid-2018: Bandcamp finally launched after years of tentatively saying "I really ought to try that"
A few group recitals with other people and one (very exhausting!) solo recital from my classical days, but I've never publicly performed my original music.
Enya, Tori Amos, Nightwish, Vanessa Carlton, Howard Shore, Trevor Morris, Solas, Within Temptation, Inon Zur, and Harry Gregson-Williams for starters...so quite a broad spectrum, really!
Fostex MR-8, dynamic microphones (...of dubious branding), Audacity, Finale, various keyboards, and quite a lot of luck.
