1. Nervo – Miriam and Olivia Nervo
Being twins isn’t the only thing that sets these performers apart from others in the industry. Starting out as songwriters in Australia, this duo of Italian descent did not receive significant critical acclaim until their collaboration with Rachel Stevens in 2005. In 2008 they received a Grammy Award for the No. 1 collaboration “When Love Takes Over” featuring Kelly Rowlands and David Guetta. Their success continues in 2015 in the studio and through live performances as well.
