"Everyone sings about something. They talk about the camps and how they look and the suffering inside them," Kassem said. "We talk about problems too, but we also talk about solutions to those problems." Kassem has just finished high school and hopes for a scholarship to enroll in college, while Turek dropped out of school at the age of 12 and got a job in a factory to support his family, including four younger siblings. Turek had no choice because his father became a victim of the periodic political and sectarian violence that afflicts Lebanon. "My father was wounded and could no longer work," said Turek, who hopes his brothers and sisters will never have to quit school. "They can't drop out of school, no matter what. They need to be better than me when they grow up." The rappers say the I-Voice message is one of unity. "Arabs need to unite, because they face the same problems that are dividing their societies," Kassem said. "Young people can change everything. Youths who are aware can make a real revolution happen and that's who we're talking to." They say they were influenced by many artists, ranging from slain rapper Tupaq Shakur to underground rapper Immortal Technique, Lebanese singer Marcel Khalife and Palestinian poet Mahmud Darwish who died last month. Kassem takes his inspiration from artists who are "brave and intellectual and exude confidence." The duo hope to link up one day with DAM, a rap group hailing from the Israeli-occupied West Bank who recently featured in a documentary that was screened in Lebanon's camps called "Slingshot Hip Hop." "We are laying down our vocals to send to them. We can't go to Palestine and they can't come here," said Kassem. "We might meet in Belgium for a joint concert, though."

With an expanding fan base, Kassem and Turek have signed deals with record companies in Jordan and Belgium. But despite their growing success, the rappers remain proud of their roots and true to their cause. "We called ourself Invincible Voice because we are the voice from the Palestinian camp that will not be silenced," said Kassem.
