Recording very Loud audio

I am trying to record very loud rock music and can not plug into the board. I am trying to find the best Microphone to do that. with out getting over driven or clipping. Can someone please help. I am recording at clubs that do not give me access to the mixer

Thanks

Nearly any mic sold has a MAX SPL figure listed in it's specs.

That's the sound pressure level it's rated at.

Small diaphragm mics tend to rate higher than large diaphragm mics, but there are units like the Sennheiser MD-421U that can handle up to (iirc) 135db without breaking a sweat. That's a level where your hearing is in instant danger. So the band should be well below that.

Next, you want to carry some form of PAD to attenuate the signal between the mic and the input if necessary. In-line switchable attenuators from TecNec or Audio Technica with 10-20-30db pads are ideal for this.

But also don't expect to get a FABULOUS "studio sounding" quality recording via Mics in a live situation. Live audio is pretty messy - being created and mixed for the crowd, rather than to be recorded and played back later for critical listening.

Good luck.

I know this isnt helpful, but the sound you will get will be truly awful no matter what mic you use. if the venue wont give you a feed off thier mixer, personally Id walk away from it - theyre a bunch of amateurs.
Find something more worthwhile to do with your time rather than persue something that is destined to fail.
Try getting your client to discuss the severe limitations that are being imposed on your product by the lack of access. If no go, id sack the in house team off the job and put in a complete rig of my own.
