Yawn.
Unless EVH somehow found Doc Brown's time machine and goes back to the early 80s, this new VH stuff won't be that same kind of fun, partying rock that they originally did with Roth. If you listen to the two new songs they did with Roth in the 90s (on the best of), they basically sounded like other 90s VH songs, but with Roth singing instead of Hagar.
Plus, while he is a very average bass player, you cannot underestimate how important Michael Anthony's background vocals were to their sound.
