Prince starts September off with "U Know." The smooth cut features a simple piano backdrop, perfect for the legendary crooner to show off his range while also experimenting with a robotic edge to his voice. The new single will appear on his upcoming solo album, Art Official Age, which drops September 30. Prince will also drop PLECTRUMELECTRUM as a member of 3RDEYEGIRL on the 30th. Both albums will be released through his deal with Warner Brothers.
