Six specially customised guitars featuring rock stars past and present will be helping raise money for charity.

Brighton artist Jan Irvine was commissioned by Hard Rock Cafe Europe to be the official illustrator for the Hard Rock Calling concert in London, which started yesterday and finishes tomorrow.

Stars taking part include Rod Stewart, The Killers and Bon Jovi.

Ms Irvine drew the performers throughout the three day concert and her portraits, along with the Fender guitars, will be signed by the stars themselves and put on display.

All proceeds will go to the music therapy charity Nordoff Robbins.

This is the second year Ms Irvine has been asked to illustrate the concert.

In 2010 she drew Stevie Wonder, Paul McCartney, Elvis Costello and Jamiroquai among others.
