July 10 is shaping up to be a fun. night in Chicago.

The Taste of Chicago 2013 is kicking off their musical line-up with the Grammy-award winning group fun. and opening act Delta Spirit on July 10. The fun. (yes, that period is supposed to be there) trio of Nate Reuess, Jack Antonoff and Andrew Dost recently won Grammy awards for Best New Artist and Song of the Year for the anthem "We Are Young" (featuring Janelle Monae).

The 5-day Taste of Chicago festival runs through July 14, and the other musical acts are expected to be announced in coming weeks, said Cindy Gatziolis, spokeswoman for the Chicago Department of Cultural Affairs & Special Events.

In 2012, after more than $1 million in losses at the 2011 Taste, the city unveiled a new, smaller Taste, cutting the 10 day festival to five days and pushing the dates back from the July 4 holiday to mid-July.

While admission to the Taste is still free, the new Taste includes a $25 ticket charge for the 3,000 pavilion seats for the mainstage acts. Lawn sets are free.

The smaller, revamped Taste of Chicago 2012 was still a money loser, losing $1.3 million, $300,000 more than 2011, though attendance and revenue were up. None of the five concerts sold out though people still crowded onto the lawn to hear acts like Jennifer Hudson for free. More than 1.2 million people went to the 2012 Taste of Chicago.

Tickets for fun. will be sold in May. Check www.tasteofchicago.us for more information.
