What are your more oddball musical ambitions? The kind of stuff most other bassists would think is weird or pointless or just plain stupid?
One of mine is to get a label to pay for a run of women's underwear with a band logo. Looks like that is going to happen soon. I've also convinced another label to put together a metal tribute to Army Of Lovers which should be out next year. A less likely dream is for a song I play on to be used in a TV commercial... that one started off with me joking that one of my pop band's droniest songs would be good for one of those weird and artsy perfume ads.
As far as ones already fulfilled, my old ambition to release something on vinyl before that medium goes the way of the dinosaurs became a reality several times. I also finally figured out how to cross hip-hop with country a few weeks ago (see
