CONCERT: Young Xenarchitects

WHEN: Friday 1 April 2011, 1pm (FREE EVENT)
Central Bar Foyer at Royal Festival Hall
More information

A dazzling programme of new music and movement inspired by Xenakis, created by talented young musicians in collaboration with sound artist Aleks Kolkowski. Ten composers, aged between 13 and 18 and drawn from both the Purcell School for Young Musicians and across the UK (in partnership with Sound & Music), have composed short pieces for instrumental sextet. The compositions are the result of experimenting with the UPIC-inspired composing program HighC, making their own drawings on computer screen and then recording the electronic sound results.

The musicians performing are the Purcell School's award-winning IMPULSE Outreach Group - young musicians who create and run their own community concerts and school workshops.

After this performance, IMPULSE will travel to Cornwall where the young musicians will introduce aspects of this fascinating project to other young composers in schools and colleges.

UPIC Workshops

WHEN: Saturday 2 April 2011 - Sunday 3 April 2011
WHERE: Sunley Pavilion at Royal Festival Hall, 10.30am. Tickets: £5
Information and booking

Originally created in the late 1970s by Xenakis as a computerised music composition tool, UPIC is based on the premise that drawing can be fundamental gesture for creation, in any domain. It has been effectively utilised by a range of users, from children to composers and sound artists. Nowadays music can be composed with UPIC using either a mouse or a graphic tablet to draw curves. In this workshop - led by composer and Xenakis expert Rodolphe Bourotte - participants have the opportunity for an intensive hands-on creating session with the latest version of the software.

Places on each three-hour workshop are very limited, and aimed at adults with an interest in music composition software, sound art and/or the work of Xenakis. You are asked to bring your own PC laptop running on Windows, and headphones. If this is not possible, please email before purchasing a workshop ticket and Southbank Centre may be able to lend a computer.
With the support of the Réseau Varèse subsidised by the Culture Programme of the European Commission.

Discovering UPIC

WHEN: Saturday 2 April 2011 - Sunday 3 April 2011
WHERE: The Front Room at Queen Elizabeth Hall, 3.30pm (FREE EVENT)
More information

UPIC, the computerised music composition tool created by Xenakis in the late 1970s, is introduced by composer Rodolphe Bourotte, who is based at the Centre Iannis Xenakis (CIX) in France. Aimed at the general public, this lively talk features audio and visual examples and demonstrations.

Bourotte studied at the Ateliers UPIC, the music centre founded by Xenakis, and has been writing electroacoustic and instrumental music since 1998. He is especially interested in new ways of considering music writing, based on controlled aleatoric events, and has developed his own computer-assisted real-time information display for performing musicians.

Talks take place on Saturday 2 and Sunday 3 April at 3.30pm in The Front Room at Queen Elizabeth Hall.
