In 2000, after a two-year sabbatical, Yanni released his first studio album in seven years: If I Could Tell You.
Yanni toured in 2003–2004 with the debut of the Ethnicity album extending his "One World, One People" philosophy. This album sparked what would become the 4th largest concert tour of the year ranked by Billboard Magazine.
On May 6, 2004, the University of Minnesota conferred upon Yanni the honorary degree of Doctor of Humane Letters.
He kicked off his 2004–2005 "Yanni Live!" tour at Mandalay Bay in Las Vegas, Nevada, and his next live album and video, Yanni Live! The Concert Event was released in 2006.
In 2008, in collaboration with producer Ric Wake, Yanni showcased vocal artists singing his songs on the album Yanni Voices. On March 24, 2009, Disney Pearl Imprint released Yanni Voices, the artist's first studio album in six years, and its Buena Vista Concerts division produced the tour that began in April 2009.
