Los Angeles, consider this a fair warning to clear your schedules.

Next week, two of the most famous musicians of our time will be performing not only live, but also free of change. Music icon Paul McCartney and pop sensation Justin Timberlake will be bringing sweet music to fans’ ears in Hollywood next week for the new season of Jimmy Kimmel Live, and we’re all invited.

According to an article via laist.com, on September 23, McCartney will interview with Kimmel, then perform for fans in an outdoor concert that will shut down all of Hollywood Blvd. Timberlake will do the same the following night, giving the audience a live taste of his new album.

As mentioned, both nights are free. If you want to go, request your complimentary tickets here. To make room for the event, Hollywood Blvd. will be closed stretching from Highland to Sycamore. See details on the ticket page regarding timing.

If you can’t make it to one, or either, then you can live stream the show via MySpace.
