Solange Knowles - Solange Knowles Joins Coca-cola Campaign For Clean Water In Africa

Beyonce's little sister, along with rocker Chris Taylor and musician Twin Shadow, appear on a new 'donate to download' single, entitled Kenya, which will raise funds for the Replenish Africa Initiative (Rain).

Fans can donate as much as they can for the track and bosses at The Coca-Cola Africa Foundation are hoping to raise $10,000 (£6,700) for clean water projects in Rwanda, Uganda and Cameroon.

Knowles says, "Water is a necessity, it's not a privilege. The 'Music for Rain' project gives everyone a chance to contribute and play a part in improving the situation."

Kenya will be ready to download on 15 March (11).
