There’s a reason Rochester is unofficially (but endearingly) known as “Festival City.” Once the first signs of spring begin to take the town, residents from the city proper as well as all those in the surrounding suburbs eagerly await the sunshine, the music, the food and the flowers of a Rochester summer. And out of all the colorful festivals the city has to offer, none are more popular than the Xerox Rochester International Jazz Festival — or the “Jazz Fest” for short.

Earlier this week, the official lineup for the 2014 Jazz Fest, which runs June 20-28 in the East End of the city, was finally announced.

Rochester’s City Newspaper reports that headliners for the festival’s thirteenth year include Steve Martin and the Steep Canyon Rangers; Buddy Guy; Earth, Wind & Fire; Michael McDonald and Janelle Monae. Those acts will perform at Kodak Hall in Rochester’s historic Eastman Theatre. So far, the Steve Martin and Earth, Wind & Fire shows have all sold out.

Other big-name artists like Big Bad Voodoo Daddy, the Marcus Miller Band, the Lou Gramm Band, Soulive and George Thorogood and the Destroyers are offering free concerts throughout the festival’s run at outdoor stages. These are only a taste of the Jazz Fest’s 75 free shows scattered throughout the East End. Indeed, it’s the free shows that tend to be the biggest draws, allowing folks to party into the late evening hours. Though a recent Gallup poll found that Americans get an average of 6.8 hours of sleep per night, during the Jazz Fest, Rochesterians understandably get a lot less.

In addition to the headliners and the free acts, the 2014 Jazz Fest will feature smaller shows from Wilco’s Nels Cline, Mingo Fishtrap, Bonerama and Snarky Puppy. Plus, the Eastman Youth Jazz Orchestra and local high schools jazz bands will be featured as well.

So, what’s new for the Jazz Fest in 2014? For one thing, the Inn on Broadway will feature a new venue called the “Squeezers Stage,” which has plans to host a showcase of jazz, blues and R&B performers. The Squeezers Stage is a new addition to list of places approved as “Club Pass” venues, or those which can only be attended by purchasing the $194 passes. In addition, four concerts in Kilbourn Hall will be taped by WXXI Public Broadcasting for national distribution through PBS stations.

All in all, the Jazz Fest promises to host over 300 concerts from nearly 1,200 musicians in the span of only nine days. So, what are you doing near the end of June this year?
