Incubus
I have liked this band ever since they came out. Saw them at Lollapalooza in Chicago years ago. Very good. The guitarist Mike Einziger is a genious. Mike actually played "Mountain Song" with Jane's Addiction during that show. Very great. As a guitar player myself I am amazed at what he can do. He writes very interesting guitar riffs, Brandon can sing his ass off around that (and play djembe), the ex Roots bassist holds it down, the dj scratches some nice Brandon vocals, and the drummer mixes between funk/latino/dnb and rock.
All of their stuff is good, but I'd say start with their new album "Light Grenades" if you have to start somewhere.
