Leica does make a camera that should work well in low (concert) light.
It is the X1.
http://www.amazon.com/Leica-X1-12-2MP-Digital-Camera/dp/B002NX13QC/ref=pd_sim_sbs_p_9
The price is about $2,000.
For low light you need:
1.
A lens that captures a lot of light.
Measured in aperture (i.e. f/2.8 is twice as bright as f/4 which is twice as bright as f/5.6)
2.
A camera sensor that is large (22.2x14.8 mm - about half the size of 35mm film)
3.
ISO settings of at least 3,200 which is twice as bright as 1,600, which is twice as bright as 800, etc)
..
The C-Lux-2 takes nice pictures, but I want a camera that takes better low light concert pictures.
Any suggestions would be appreciated.
