As well as being able to offer my services as a Videographer, I am also a Live Sound Engineer and Music Producer.
I can offer a multicam, Cinema 4k recording of the music performances and would be happy to also take drone footage of the festival. Additionally, I can take a multitrack mix of the recording, assuming a modern digital mixing desk is used, and produce a high quality, mixed down audio recording of the performances to sync with the video.
If you do require assistance editing, I can also augment footage with slick animated titles/motion graphics.
