I plan on recording a live outdoor concert on 7/17 and need some tips on how to get and make the best recording. I have a Sony Portable MiniDisc Recorder (MZ-R37), 2 good quality mics and a battery box with bass roll-off filter. These are all the things I was told I would need to do a good job. Now all I need is some experinced live recorders to give some tips on how to get in with this equipment and make a good recording. Thanks.
