Funnily enough, the only reason I went to that show was having watched their previous acoustic tour on YouTube. The quality obviously blows a phone recording out of the water, I wish more concerts did this.

If anyone finds an Acoustic II concert video around, let me know.
EDIT: well timed, just looked again and I guess it's more of a documentary with showings starting next week: http://www.aboveandbeyond.nu/acousticfilm/
Bit of a slow turnaround from a show in May 2016.
