I have always wondered how you all cut together the segments of a live band. I normally will shoot 2-3 songs of just the band, then cut the appropriate dancing around it.
I shot this during my May 30 wedding in florida. I used a zoom h2 connected to the band's board for sound, mixed with some ambient.
