Brett Dennen is a modern day rockstar. Instead of sex and drugs, he's into living healthy, cooking from his backyard garden, and eating mostly raw. Does that make him totally uncool, or just a too-unusual role model?

Brett is currently on tour with Reverb, a Maine nonprofit that greens concert tours and venues, including for artists like Dave Matthews Band. Brett is on the Matthews' Caravan tour this year as well.

So Brett, all healthy and raw, must just be in it for the money, right? The lavish lifestyle? It turns out that he's been selling Klean Kanteen reusable water bottles at his shows, and sending partial proceeds to The Mosaic Project, which "empowers children to create peace now, build communities across differences, and break down stereotyping, prejudice, and discrimination." Low-income students will use the proceeds to attend a unique human relations outdoor school, Brett says on his website.

Also, the profits made from at-show and online sales of his newest CD "Loverboy" (also available on good ol' vinyl) are being donated to another nonprofit, Invisible Children, which is working to bring an end to the abduction of kids in Africa, where they're made into child soldiers.

The Invisible Children blog is calling for "Brett Dennen For President" based on his efforts.

Besides "Loverboy," Dennen also has recorded campfire songs for Mosaic Project kids about "empathy, diversity, conflict resolution, and peace." Compare that to your modern-day R-Rated pop music. Remember when lyrics were subtle?
