I grew up on musicals, and I know they are quite the thing now, but I'm actually a little indignant, because I started taking singing lessons years ago - I put the time in! ↗
Now I'm fortunate to have a good band in CA, and play many solo gigs as well. My point is that I stopped playing in bands and played solo for four years, to get back into the groove and pulse of writing and singing and who I am on stage. ↗
I studied German at school. I lived in Berlin for two years and had a German girlfriend for five years, so I don't find speaking German particularly difficult. Singing was slightly more difficult. ↗
My stuff was more of a folk coffeehouse thing, with more acoustic guitar, just me doing a single, and then adding on instruments and voices, with emphasis on lyrics and singing and light kind of acoustic jazz. ↗
