Rap duo Macklemore and Ryan Lewis have teamed up with producers of Broadway play Mothers And Sons for a special Hiv/Aids fundraiser.

Producer Lewis launched his own charity, the 30/30 Project, in April (14), after revealing his mother, Julie, has been Hiv positive for 30 years.

After smashing a crowdfunding campaign goal to raise $100,000 (£62,500) to help build a health centre in Africa, the Same Love hitmakers are now working with bosses of the Tony-nominated play to bring in more money for the cause.

Mothers and Sons, which features veteran actress Tyne Daly, centres on a mother who returns to New York City years after her son died from Aids, to visit his former partner who is now married with a son.

MACklemore and Lewis praise the play in a statement, which reads: "This vital play keeps the message going strong, and we are proud to lend our voices to help this cause."

On 11 June (14), post-show donations will be collected, and all the money received from merchandise sold will go towards 30/30. In addition, Lewis' mother Julie will join the cast for a post-show talk to discuss the work of her son's charity.

The aim of The 30/30 Project is to open at least four health centres in Kenya and Uganda in the coming years in a bid to provide support and treatment to sufferers of the disease over the next three decades.

The centres will be built in partnership with officials at Construction for Change, a non-profit organisation based in the duo's hometown of Seattle, Washington.
