Neither cameras are capable of taking good photos for concerts where lighting is often poor if not dismal, especially when the camera lens is zoomed out to its maximum. It's not a knock on these cameras. Even if you use a tripod, you may get more sharper overall image but since the shutter speed will be low due to poor lighting, moving objects and people will still come out blurry. Even DSLRs will need special pro caliber, "fast" lenses to capture concert images clearly.
They will both take excellent pictures even at its maximum zoom setting when the lighting is good such as sunny day ouside, preferably mounted on a tripod.
You will need a P&S camera with fast lens such as Canon S100 or Nikon P310 and be more up close to the concert action to take potentially sharper photos. Otherwise, most all P&S cameras will come out blurry. Concerts are one of the toughest settings to take sharp photos.
