Spirit of Gravity, Marlborough Theatre, Brighton, Tuesday 18th July

With June's strange lurch towards (but admittedly not into) orthodoxy behind us July saw us right back on the fringes again. Indeed, the kind of night that takes the "m" clear out of experiental music.

Starting the evening with a completely new approach to his music Dan Powell (www.myspace.com/danpowell) with a small array of percussion, microphones and digital trickery gave us a set of delicate sounds grouped and marshalled via the laptop into slight, beguiling palaces of shimmering light. Insubstantial, wistful: permanently vanishing set pieces of loveliness - they were here, and, all too soon, they were gone.

With another new Sitar, possibly even lovelier than the last, Same Actor (www.hotroddy.com) started his set with a tribute to the late Georgy Ligeti taking some of the density and repetition of the late masters work into his own sound. With Chris talking us through the pieces in his introductions he rounded his set out with Max MSP processed Sitar, usually plucked, although occasionally tapped and patted, into entwining layers of sound. I've heard a preview of his impending release on the Wrong Music label as Hot Roddy. Fantastic, it will be his best release yet.

Halal Kebab Hut (www.simonkatan.co.uk/HKH/) were seven people in corporate Red or yellow baseball caps sat behind three tables piled high with toys, junk, whistles and...things of every colour and shape. In front of their semicircle on a podium sat an open laptop, like a conductor. Although some other people also conducted. I imagine that the computer issued instructions of some sort. I also found a piece of paper with written instructions that was reclaimed while I wasn't looking, not that it illuminated things anyway. There seemed to be some kind of Fluxus thing going on, between the fixed instructions of the sheet, the dynamic instructions from the machine and the freeform instincts and abilities of the musicians performing. Not that they had musical instruments(www.simonkatan.co.uk/HKH/writings/HKHtechniques.pdf). There was a lot of standing up and sitting down, some conducting, some singing and talking, some musicalness for sure. Some Cuckoo sounds, too. Arms were raised, rude gestures made, people waved and pointed to their noses. And laughed. It was endlessly fascinating to watch: funny, riveting, mesmerising.

All in all, a very pleasurable evening to experience, in spite of the blistering heat.
