My parents encouraged me to learn music, and supported my study of a couple of different instruments. My mom even accompanied me to W 48th St when I bought my first real amp and cab (can you say Peavey Mk IV and 1516?) and helped me get the gear home (at least hailed and paid for the taxi...). That said, my mom has always said she has no ear for music, and my dad (RIP) listened to music tons at home. Plenty of classical records spun on the turntable.
My mother never has come to a gig, and I expect she never will. My dad never saw me play until I hit my late 30s, and it was great to see him out at a couple of Lower Eastside clubs in his 80s, usually talking to the bartender about how he used to listen to me practicing piano and trumpet as a kid, "but look at him now!"
Next will be for my kids to see me play a gig...
