I saw Coldplay in L.A. with Pete Yorn, but never with DMB. Have you heard O.A.R.? I would think they might appeal to you if you like DMB shows. If you ever get the chance, go to one of their concerts. They're one of the best live concert experiences I've ever had - it's much like what I would imagine the 60s and 70s concerts to be like in terms of atmosphere. They're very much like the Dave Matthews band, not just sound-wise, but also because the energy I feel at their concert is so vibrant and contageous. Their CD (In Betwen Now and Then - http://www.ofarevolution.com) a good job of capturing their live sound. I was relieved to find that their live energy translates in the studio - since it's their first major label deal, I wasn't sure if the CD would do the live show justice, but it does. But definitely go to one of their concerts if you can, it's incredible.
