Some guys just can’t get enough.

For some frontmen, it goes like this: Form a band; spend thankless years toiling in empty clubs; catch a big break; make it into the mainstream; rise to become a full-fledged, card-carrying rock star; then promptly step aside from the band to completely reinvent yourself with a different sound entirely.

Sometimes it’s creative stagnation that leads to side-projects, other times it’s just boredom. But there’s no shortage of famous frontmen who have recently done double-duty with both their main outfits and more self-indulgent projects on the side.
