Founded three years ago by Si Chai, today, Chai Wallahs attend a number of summer calendar events - including Green Man in the Brecon Beacons - and are quickly becoming seek-out destinations.
Inside the organic-looking structure Afro-beat, funk and reggae artists perform alongside DJs in a free-form mix, with the emphasis on acoustic music earlier in the day. It also provides its own chill area in the form of a café bar.
Green Man has become one of Chai Wallahs' more recent destinations, and after their debut last year, this summer they were again out in force, with London-based sound engineer Harry Bishop piloting a Soundcraft Vi4 in the 800-capacity tent.
"The Soundcraft Vi is my weapon of choice," said Bishop, who last year took Soundcraft's original Vi6 digital desk around the festival circuit.
This time around the Soundcraft Vi4 had been sub-hired in from Mark Hornsby's PA company Hark, with whom the sound engineer has a close relationship. Hark also provided a Vi6 and Vi1 at Green Man's second stage (the Far Out Tent).
