Before the horses get a chance to do their thing in the $1 million Preakness Stakes, the Pimlico Race Track in Baltimore will feature performances by Rock and Roll Hall of Famers ZZ Top and Grammy-nominated Buckcherry.

A third artist will be added to the show at a later date.

“The Preakness Stakes is the biggest single-day sporting event in the state with attendance figures exceeding 100,000 nine of the last 10 years, including eight straight,” Maryland Jockey Club president and chief operating officer Tom Chuckas said in a statement.

“In 100 days, the best three-year-old horses will be in Baltimore and we feel it is time for our public Infield customers to enjoy a new way to party. In this year of change it is now time to transform the Preakness Infield experience.”

The 134th InfieldFest is also bringing in more than 240 tons of sand to construct an Olympic-size court for a professional women’s beach volleyball doubles tournament, the first spot on the Toyota Pro Beach East Volleyball Tour’s 2009 season. The tournament is from 9 a.m. to 5 p.m. with free seating around the court.

An interactive area will feature RockStar Guitar Hero, an authentic NASCAR vehicle that participants can take for a virtual test drive, and virtual paintball. Oxygen bars, which will be equipped with charge pods for phones, PDAs and iPods, will serve flavored O2.

Tickets for public Infield are $50 in advance and $60 day of show. Top of the Stretch seats are $110.
