Thank You So Much, I was at the show my first GN'R show now immortalized. This is a great recording for being recorded at a low bit rate on an iphone/ipod touch. Seriously impressed, very clear and I've heard supposedly better quality recordings that sound much, much worse. Awesome Job!
To clarify my comments I don't know anything about equipment used or how to record a show with quality. Just going by bit rate. All I know is that this is a good sounding recording.
