Whether the crowd who turned up to see Fripp plug his Les Paul into the two Revox tape recorders that Thursday in 1979 expected what they got is a matter of speculation. However, the yelp of shock quickly followed by applause from the audience when the swirl of arcing guitar abruptly cuts out after Loop and solo pass 1 suggests they were pretty pleased about it all.
This is a classic Frippertronics concert painstakingly restored by Alex Mundy from the source reels and audience recordings wherein short and long lines accrue like a febrile morse code transmitting strange signals, gathering together in vibrant, intense clusters underpinned by the rippling undertow of bass. Hindsight lends us a degree of familiarity with the process yet despite this the way in which notes flicker delicately like a candle in the wind to then suddenly take on the ferocity of a blow torch is still breathtaking stuff.
