One of the biggest music festivals in the country will get even bigger next year.
Lollapalooza , celebrating its 25th year in 2016, announced that it will offer musical acts Thursday through Sunday, instead of kicking off the festival on a Friday.
The festival is scheduled for July 28-31 in Chicago's Grant Park.
Festival organizers say the 2016 edition will feature more than 170 musical performances.
Four-day admission tickets start at $335 and will be available in the spring.
The festival annually sells out its daily capacity of 100,000.
It's not clear if the four-day format is only a one-year deal. Lollapalooza has made its home in Chicago since 2005 after its initial incarnation as a traveling festival.
