Im not sure how famous he is last I remember he as picking up fame pretty quick. The fist time I heard Brett Dennen he was opeing for Colbie Callet who was opening for John Mayer. I was with 2 of my brothers and neither of them liked him but I really did. They later ate there words when the music began to grow on them. I knew a few friends in high school who knew him and I think he is pretty popular now. Anyway here are a few of his songs. This one is "Shes Mine" - one of his more popular ones but I really like this one.
K keep in mind he is kind of a weird looking chubby redhead with really long hair ha so heads up. Ha this one I actually posted the music video. This is probably he most famous song called "Aint no reason"
This next one he played at his concert and it was pretty good I liked the way he did it at the concert better but here is the recorded version.
This one is called "heaven" its prett cool.
Here is the acoustic version I found next to it its pretty cool
