Well, the "Broon" part comes from a once long time producer for my favourite band, RUSH. He was a good ol' Scotsman named Terry Brown but in his thick Scottish accent he pronounced it "Broon." A classical guitar intro to one of Rush's songs is called BroonsBane.
I've had several things in my life become the "bane" of my existence over the years and I won't bore you guys with the details so I just put the 2 of them together. I've been using BroonsBane for a long time now...almost my alter ego!
I like the name because both parts have some personal meaning for me.
