ALT.ROCK Alt-J Unassuming and unaffected they may be, but this Leeds band (led by Joe Newman, right) continue to impress with their second album, This Is All Yours, which is resolutely odd but often gorgeous. However, is the 3Arena too big for the band’s subtleties? Put it this way: We predict a “theatre-style” setting. ROCK GANGS We like bands who dress sharp and who are sussed enough to cater for the younger fan. Dublin band Gangs perform two gigs here – 2pm for the, er, kids, and 7pm for the slightly older kids. Officially, the band launch their debut EP, Back to School (which is produced by Blades member Brian Foley). Unofficially? Could also be the launch of a very promising career. TECHNO Truss Tom Russell’s take on the hard stuff has won many converts over the years. In addition to storming venues like this (his previous visit for a Subject night was a bit of a frenzy), Russell’s tough techno has also won him an appreciative audience via releases as Truss and MPIA3 for such well-regarded imprints as Donor’s Miniscule label, Perc Trax, Synewave and R&S. Support tonight from longstanding Dublin tech DJ and producer Sunil Sharpe and Subject’s Eavan. HOUSE Kant Danish DJ Joachim Schaarup kicks off a monthly residency tonight at the new weekly bash from the Sense & Bedlam crews in the Button Factory. Kant means “edge” in Danish, and you can see that the Copenhagen-based DJ and producer lives up to his name with his take on new-school house via various mixes and releases for Suara and Berlin’s Katermukke label. Support from MTA and OFF dude Josh Butler, RTE Pulse’s Dan Stritch and Bedlam DJs. TRADITIONAL Alan Kelly Gang Kelly has rehabilitated the piano accordion, dragging it kicking and screaming into some of the most spine-tingling sessions and concerts, more recently in the company of Eddi Reader (below). The band’s latest CD, The Last Bell, chronicles a collective still in thrall of the live performance over all else. At the heart of it is Kelly’s musicianship. JAZZ Limerick Jazz Festival The excellent Dublin City Jazz Orchestra, led by Pete Churchill, and Nigel Mooney’s storming septet with guest saxophonist Julian Siegel get things swinging tonight. Superstar sax man David Sanborn’s trio with Hammond organ master Joey DeFrancesco are Saturday’s headliners, with a late-night set from an all-star band led by artist-in-residence Siegel and Richie Buckley. If These Spasms Could Speak “It’s like they’re so scared to be caught staring, they’ll do anything to avoid looking at me,” says Robert Softley in his collection of stories of disabled people. “It’s like I’m invisible to them.” Softley, a Scottish artist with cerebral palsy, would like to challenge that with this wry and charming performance, an exaltation of living.
