More info is needed to help with your diagnosis. When you recorded the music, did you see the level meters moving on the R-09's meter? If so, your mics were functioning, so maybe the issue is with the SC card.
If you didn't have any levels, then perhaps you weren't powering the mics properly. Your microphones need to be powered in order to function properly. On the R-09, you have the option of plugging your microphones into two jacks; Line In, or Mic In. If you used Line In, you wouldn't have had anything to power the mics since apparently you didn't use an external preamp or battery box. If you used mic in, that does provide voltage to power the mics, but oftentimes it's not enough for loud rock concerts and your mics will distort. (Note this wasn't your problem though since you apparently had no levels). To prevent that, most people get an external powering solution, such as a battery box (which just provides phantom power only) or a preamp (which provides phantom power AND signal gain). In that case, you should use the Line In jack.
