Please help

I go to alot of music gigs and want a new camera but can't decide what to buy, everybody writes about nature and sports pics which are completely different light. All I do know is that I want

Great pictures of the band or close up of friends
video
zoom - as I am too old to stand at the front anymore (i want great zoom without loosing pic quality)
sound - for video
flash or help with taking better pictures when background is bright
automatic focus but not of the nearest object
stabilisation to stop fuzzy pictures


I have looked at Panasonic Lumix DMC-FZ38 x18 zoom & Olympus SP-590 x26 zoom but i'm sure i'm missing other possible candidates
