It's the 20th festival on Knockengorroch Farm and glorious sunshine lights up the hills. Like a secret Garden, twice yearly this isolated glen is repopulated with a kaleidoscopic mix of hippie chicks, folky families and roots music believers.

Friday headliners' Dreadzone sound as fresh today as they did in the 90's. MC Spee waves his crutches like a pirate, addressing the crowd with the call: "ahoy me hearties", warming us up for the weekend, and the festival season ahead.

Saturday kicks off with Asazi Space Funk Explosion. On 'Madafaka', Asazi sings "if you call me a hippie, watch your back/That stereo you love so much, I sold it for crack" – it's world music, but without airs and graces.
Thinking I hear another band starting, I move. Amazingly the sound is all coming from one man's mouth. With a microphone to his mouth and one to his neck beat-boxer Shlomo is a human juke box, even blasting out White Stripes hit 'Seven Nation Army'. Later he extends his multitasking ability by using live loop-sampling technology to build up layers of mouth made sound – he's good, and he knows it.

Capercaillie headline on Saturday and like their namesake, Karen Matheson's haunting vocals belong to the hills. It's the perfect mid evening chill. Later, the Peatbog Faeries set the heather on fire with furious fiddling to get our feet moving.

At midnight the crowd splits and the children are packed off to bed, exhausted after a days entertainment of storytellers' and workshops. Glasgow's Mungos Hi Fi oversee matters in the Sheiling tent, as dub steppers thrash their dreads to bass lines you can feel in your colon. Meanwhile the Long House hosts an ongoing folk session and with the fire stoked, we contemplate whether sleep is really necessary.

Security stop us to insist that we have a good time and the last I saw the police they were checking the festival programme to plan their evening. Too soon it's time to say "goodbye Knock', see you in September". You never know, the weather might last.
