Soon to be touring under Porcupine Tree, Rose Kemp gives festival-goers a bare-bones performance, sometimes offsetting her naturally powerful voice with the crunch and subsequent feedback of a distorted and slightly downtuned telecaster and even casting the guitar aside to go a capella, her soulful folky voice being the axis of this set. In the characterestic contrast of the weekend Diagonal follow this up with proggy spacey 70's style classic rock from a Brighton-based seven-strong band of talented musicians. Epic songs with extended instrumental sections are only held back from all out hippie nirvana by some abrasive overdriven guitars. The sum of many parts including: keyboards, synths, alto sax and some inventive melodies mean this is a great nostalgic-sounding band who are still young!

  Tartufi are a duo from San Francisco who play the guitar, bass, keyboard and drums between them, sometimes while singing harmonies with themselves. Acheived using looping equipment, the result is an uplifting musical landscape, like a garden that grows in unexpected ways. Lynne Angel's vocals call out stirringly in solemn syllabic phrases while the layered rythms from drummer Brian Gorman are the primal backbone to some memorably experimental songs.

  The facetiously named Master Musicians of Bukkake have a surprisingly tempered and atmospheric sound, as they craft edgy ambience out of miscellaneous sources. Standing in a red mist and dressed in beekeepers outfits of course. All girl Tokyo trio Nisennenmondai trade in harshly trebly guitar parts, fast and simple drums and inventively melodic bass lines. And a great deal of repetition, as delay pedals layer up plinky and scratchy guitar parts and Sayaka Himeno attacks her hi-hat like a Japanese 'Animal' from The Muppets. Another of the festivals many small groups, Iron Lung rely on no looping software to create believably chunky and heavy songs between the two of them. Glib and chatty between songs, but each track a furious release of frustrations that gets a lot of the metallers in the crowd going.

  The sounds manipulated by Norweigan artist/graphic designer Kim Hiorthoy in his set of electronica have a nostalgic 8-bit games console feel to them despite being modern, sometimes glitchy, arrangements. Light and airy in the face of the crowded dance sound Hiorthoy's music is a lot of fun and keeps the Factory Club stage warm for the time being.

  Back in the Space 2 stage 80's innovators The Accused play their first UK gig in some years. Sounding less punk and more thrash this heavy set goes balls to the wall with confident musicianship (including some great drumming made to look effortless by Mike Peterson) and some in-the-face rasping vocals from new singer Brad Mowen. Headlining this stage are two very similar bands (shocking I know) playing back to back heavy doom. Thorr's Hammer features the SUNN O)) guitarists (sans robes) and demonic female vocalist Runhild Gammelsæter. As sludgy doom riffs roll inexorably like thunder the vocals are used very instrumentally; dull-edged growls and mournful husky lamentations decorate the rumbling snails pace of this theatrical band. Mythic Japanese doomers Corrupted follow with their much anticipated UK debut. Bathed in cold blue light they do sound very similar to Thorr's Hammer and lack some of the dramatic edge, playing a somewhat impersonal show. After two sets of slow dirges any viewer can see why the mixing of styles at this festival is so applauded.

  With things wrapping up for the Saturday - definitely the biggest day of the weekend - instrumental Italian trio ZU take to the main stage. These three broadcast attention-grabbing organised chaos, the relentless rhythm like an alarm bell screaming: 'GTFO! ASAP!' However, if you were to evacuate you'd be missing one of the most unique acts in a weekend that runs the gamut. Highly versatile bassist Massimo Pupillo coaxes all sorts of gritty harmonics and weightily guttural bass explosions from his Jaydee bass, gluing these expertly to the confidently bizarre drum patterns. Luca Mai's baritone saxophone colours this framework with brazen, dirty sounds and lung-popping squealing runs. ZU's hard to define jazz/prog/post rock is an incredible live experience.

  Speaking of experiences, don't go home quite yet because Monotonix are setting up camp in the audience of the outside stage. These crazy Israelis play the sort of sleazy and punky rock and roll that would be met with boredom if it wasn't for the fact that the whole crowd is their playground. The drum kit is dismantled and carried around the to the back of the tent while lunatic vocalist Levi is on a perpetual crowdsurfing mission. It's difficult to avoid raising a smile at the antics and the eager audience participation, even when what the 3 actual band members are playing degrades into a mess (which is what's going to happen when you try to drum from someones shoulders). An anarchic party atmosphere, ultimately it is a bit of a comedy act but Supersonic can count another memorable live experience.
