IPhone microphone to record video at a Rave?

I recorded with my IPhone 4s on Drum and Bass night in Fabric London and the videos came out very well, also the sound was great but where the bass was very high it doesn't sound that good and was wondering if anyone knows which microphone are great for rave recording that the sound sounds amazing.

Well your obviously going to need a better mic than an iPhone. If you really want to invest I recommend a low frequency mic such as a kick drum mic.
