Triptych - Glasgow (web version)

Consistently impressive in its balance of artistic merit and unrefined adoration of good music, this year's Triptych sees some of the finest proponents of both hitting a spree of venues across Scotland. Deconstructionists in the truest sense, wrecking London's ICA with power tools and sledgehammers in '84 under the title Concerto for Voice and Machinery, soviet-era relics Einsturzende Neubauten resurrect their throbbing noise-beast for one last slog across the globe. EndeNeu were crucial in the formation of the West German experimental arts scene that gave the world Die Tödliche Doris, Kosmonautentraume, Christiane F and all the other lunatics Richard D James and Mike Paradinas were dreaming of back when they still wetting the bed. As vital and invigorating as a pure adrenal gland at 5am, this deserves your attention (The Tramway, 7.30pm, £18, 25 Apr).

Twisting and warping boundaries in the footsteps of the visionary Blixa, Boom Bip is one of hip-hop's most unnerving and consistently unpredictable exponents, a sound artist, attention deficit noisemaker, and headbanger somehow crammed into one contradictory earful of resonating rhythms. His most successful work was the heaving grotesquery spawned by collaborating with avant-MC Doseone: Circle was an impenetrable mess of gnarled rhythms, nauseous spitting and melancholy wails that left fans of every genre certain this was a force to be reckoned with. The 2004 '28:06:42:12' release, which saw him trading blows with Daedalus, proved that this wasn't some anarchistic 'Wigga' upstart, but a genuine innovator who knew his hip-hop inside out. Hollon has consistently pushed boundaries and kept alive the legacy of the acid-fried genre-benders like Zappa, Mike Patton and Ian Anderson. Though the name parodies the ubiquitous beats of all rap, his latest work was a raised two fingers to hip-hop conformism and saw him collaborating with Gruff-Rhys of the Super Furry Animals. A mix of esoteric Welsh folk and pulsing riddims (some call it hip-hobbit), this fine hybrid of noise-core and delicate melodies should appeal to fans of Dabrye, Sileni or Edinburgh's rising stars, Double Helix (w/ Gruff Rhys - see Sounds for more details. Tramway, 7pm, £14, 28 Apr). And just to prove that Triptych really has its fingers on the latest musical pulse, there's monster dubstep extravaganzas hitting Edinburgh and Glasgow, with local boys the Electric Eliminators unifying the whole event (Classic Grand, 11pm, 28 Apr).

The strength-in-every-department theme continues in terms of house and electro, with some of the world's best treating the expectant Scottish crowd to some mouthwatering nights. Amongst the numerous performers is the legendary Andrew Weatherall - who diligently crafted his position as a celebrated part of the club scene (Classic Grand, 7.30pm, £12, 27 Apr). His remix duties have included the likes of New Order and the Happy Mondays, but he is especially known for his work as part of Two Lone Swordsmen and previous incarnation, Boys' Own Collective. He'll be playing acid-house, techno, indie rock and much more, as part of Billy Childish and the Musicians of the British Empire Night.

Also appearing in both cities is Erol Alkan: gaining popularity all the time, his delightful electro, techno, remix and mashup-infused sets have become a firm favourite at Glasgow's Death Disco and venues across Europe. His set at the intimate Hold venue under The Admiral in Glasgow is sure to be a very special Friday night (Beyond The Wizard's Sleeve: Erol Alkan & Richard Norris, The Hold, 10pm-3am, £8, 29 Apr)!

Another very special guest exclusive to Glasgow is Parisian deep house legend Etienne De Crecy (The Art School, 11pm-3am, £7, 28 Apr). He's best know in the mainstream for his Super Discount albums and appearances but you may also know him by his other monikers Motorbass and Minos Pour Main Basse. Based in the French capital where he has collaborated with the best in French dance - including Air and more significantly, Cassius on the second Super Discount album - his appearance at the atmospheric Art School in Glasgow will be a true show of quality.

And lastly, one of the most intriguing acts to be appearing is a four-piece free from pretention and big on tunes - Spektrum's sound is a clash of electro, funk, punk and a good bit more (Classic Grand, 11pm-3am, £12, 28 Apr) - get down for the quality live show and tracks from their second album Fun at the Gymkhana Club: disco funkiness at its most flavoursome. A long weekend of fun is in store for the streets of Glasgow and Scotland's other major cities with this lot playing and much, much more - so be sure to check out the listings and take your pick.
