Stars of the Concert for Peace in Darfur

Born in Iran and raised in Britain, Sami Yusuf has sold more than three million albums and is a household name in the Gulf States, Turkey and Egypt. The singer-songwriter draws on Eastern and Western genres of music, switching between Arabic and English when singing. His videos are a hit with the Muslim YouTube generation, and he has snaffled deals with Vodafone. He has no Myspace page, but Googling his name yields 1,370,000 results. Photograph: Stringer/Getty

This qualified lawyer from Oklahoma is America’s first Muslim country and western singer. Impeccably polite and boasting a deep Southern drawl, Kareem Salama is on the cusp of mainstream success and in talks with a major country and western label. He does have a modest collection of Stetsons. Will throw in the odd Green Day song during a set (at Wembley it was Time of Your Life, to the confusion of the audience) but generally sings about fighting in Iraq, heartache and being good to his mama.

Outlandish are a multi-faith hip-hop group from Denmark consisting of Isam Bachiri, Waqas Ali Qadri and Lenny Martinez. All three are religious and open-minded, with Isam and Waqas being Muslim and Lenny being Catholic. The boys take their influence from their various backgrounds (Moroccan, Pakistani and Latin American) and although their songs are primarily in English, they usually feature lyrics in Spanish, Urdu, Danish and Arabic.

Hamza Robertson was born in Chadderton, Lancashire, and was raised in a predominantly white, Christian environment. Musical from an early age, Robertson played in bands and performed vocals with various groups. He became a Muslim after traveling to the Middle East. He was spotted by Yusuf Islam, the granddaddy of Muslim pop stars, and signed up as his protégé. Robertson sings about the wonder of Islam in nasheeds – a devotional form of music. Photograph: PR

The Sound of Reason are a worthy Canadian duo tackling issues such as faith and politics through a curious hybrid of hip-hop and schmaltz. Think Boyz II Men meets Yusuf Islam. Their song Palestine has had 117,404 plays on Myspace. A much better, angrier, listen is Rise, about the Israeli occupation: 'But I’ve found that the time is now to rise up and un-oppress ourselves/But we can change the times ride the tides of change/Fight them to the death ‘til we’re all the same.'
