(CNN)– Grammy-Award winning musician Jay-Z is set to host a voter registration rally and concert for Sen. Barack Obama in Miami on Sunday.
The event, "Last Chance for Change," is free to those 18 and older, in an attempt to encourage young voters to register before the state's October 6 registration deadline according to a press release.
Florida and its 27 electoral votes have been critical in past elections. According to CNN's electoral map the state is currently a toss up between John McCain and Barack Obama.

Music legends Bruce Springsteen and Billy Joel will also be teaming up for the Democratic nominee later this month.
The event, "Change Rocks," will take place at the famed Hammerstein Ballroom in New York City on October 16, the night after the final presidential debate in Hempstead, New York.
Unlike Jay-Z's registration rally, seeing Joel and Springsteen perform is not free to the public. Tickets are selling anywhere from $500 to $10,000.
Springsteen is also expected to join Obama in Philadelphia Saturday, for a free concert before Pennsylvania voters.
"Senator Obama is a great fan of Bruce Springsteen and is honored to have his support. This will be a great opportunity to gather tens of thousands of our supporters together in one place as we register new voters and bring new volunteers into this campaign for change," said Craig Schirmer, the Pennsylvania State Director of the Obama-Biden campaign.
