It was not uncommon to see famous artists, professional athletes and politicians at the Mason Jar. The Mason Jar was a favorite launching ground of music industry execs like Jenna Adler of Creative Artist's Ageny (Papa Roach, The Apex Theory) record labels like Sony and DreamWorks, management agencies like Sanctuary Music (Rob Halford) and of concert promoters like Danny Zelisko, owner of “Evening Star Productions” (now merged with Live Nation) Tom Lapenna and Wil Anderson of Lucky Man Concerts, Kim Larowe of 13th Floor Entertainment and many, many more. Mick honored The Mason Jar's roots by hosting acts like Megadeth, The Ramones, Rob Halford, Dishwalla, Frank Black, Vanilla Ice, Stephen Pearcy, Ice-T, Robby Krieger and many, many others. Mick's appetite for diversity brought The Mason Jar into new genres including country music with acts like David Allan Coe, Hank Williams III and Shooter Jennings.
Mick gave The Mason Jar a badly needed face lift, a substantial sound system upgrade and a new contemporary list of rising stars to hit the stage like, Linkin Park, Papa Roach, Fall Out Boy, Jimmy Eat World, Opeth, 30 Seconds to Mars and many more. The Mason Jar experienced a resurgence as top Phoenix live music venue with the start of the new millennium, when in 2000 the club was bought by local businessman Michael Manfredi aka "Mick". Jason Newsted of Flotsam and Jetsam, who later became the bass player for Metallica, was a regular at the Mason Jar.
Local bands such as Surgical Steel, Flotsam and Jetsam The Results and Sacred Reich also played there. Scores of bands played at the Mason Jar before they made it big, such as Tool, Green Day, Kid Rock, Rage Against the Machine, Jane's Addiction and Guns N' Roses. Whatever the reason for passing through Phoenix, all bands somehow made their way to the Mason Jar and the club became world-renowned in the process. Some simply ran out of money, never making it to Los Angeles, and others simply liked Phoenix and decided to stay and made it their permanent home. Many bands came to the “world famous” Mason Jar on their way to Sunset Strip in Hollywood, California.
He often wore his famous clog shoes, or “klags.” Many patrons had just as much fun engaging with Franco on numerous conversations over seventy-five cent Kamikaze (cocktail) shots.
He certainly made the place all the more lively with his dry sense of humor and thick Sicilian accent. Gagliano was known for his pizazz, personality and his love–hate relationships with the bands that played at the Mason Jar. Franco, originally from Sicily, who was a legend in his own right, managed the club from inception until the year 2000. Franko is credited with growing the club and making the small venue a success with national touring bands. Founded by Clyde Shields and sold to Franco Gagliano after a couple years in business.
