Leave it to Father John Misty to properly sum up the inaugural First City Festival in Monterey.

"If you can't have fun at this festival, there is probably something deeply wrong with you," the acclaimed folk-rock singer said during his set midway through the first day of First City.

Indeed, Saturday's show -- which offered up 18 indie/alt-pop acts performing on three stages -- was a definite blast. The good tunes were only outnumbered by the good times, as some 10,000 fans turned out to see such artists as Passion Pit, MGMT, Beach House, Delta Spirit and Washed Out. The action was scheduled to continue on Sunday with the likes of Modest Mouse, Purity Ring, Neko Case, Lucero and Devendra Banhart.

The few minor problems on Saturday, such as some technical glitches that caused delays on the stages, were more than outweighed by everything else. The vibe was enjoyably mellow and the crowd seemed happy and well-behaved. Plus, the weather was perfect. It was one of those warm, clear days that made you wonder why everyone doesn't live in Monterey. (Then, of course, you remember the housing prices and you understand why.)

The setting -- the Monterey County Fairgrounds, also the home of the city's annual jazz festival -- was a splendid place to gather for a "boutique" rock show. It's an intimate spot that allows you to saunter between all three stages in a matter of minutes.

It was also well decorated for the occasion -- with the rides, food stands and games in place for the upcoming Monterey County Fair, which opens Wednesday and runs through Sept. 2. That meant fans could nosh on such delicacies as corn dogs, candy apples and churros while grooving to Okkervil River. They could brave the Haunted Mansion or compete in a game of chance, with the goal of winning a giant stuffed frog or other equally desirable prize, then go rock to the Black Angels. Add in some food trucks, just so the Bay Area hipsters would feel at home, and it was truly a delicious production for fans.

The festival, however, wasn't just a hit with music lovers. It was also a hit with the music makers.

"Good job, festival!" remarked vocalist Victoria Legrand during the winning set by her dream-pop act Beach House. "Give your festival a pat on the back."

That's just what I intend to do. So, here are some of my favorite moments of the day:

Tennis -- Things just weren't going Alaina Moore's way. The vocalist said she'd been robbed a day or so earlier in San Francisco, with the culprits running off with her clothes. Plus, her keyboard kept blowing fuses, which caused delays during Tennis' set. Still, she was able to lead Tennis in a mighty enjoyable collection of bright indie-pop gems. Moore would later write on Tennis' twitter page, "Wow @FirstCityFest thanks for being the best, most understanding crowd! Broken keyboard? No problem!"

Washed Out -- The dreamy synth-pop artist, whose real name is Ernest Greene, was performing his first show in some eight months. The layoff didn't hurt him — or his backing band — one bit. Washed Out mesmerized the crowd with gorgeous numbers from his two-album catalog, which includes the recently released "Paracosm."

Beach House -- Admittedly, it's a bit strange watching this dream-pop duo perform while it's still light outside. Yet, Legrand and partner Alex Scally were able to masterfully re-create the lush magic of their studio recordings on the live stage.

Father John Misty -- I'm not a fan of Misty's music. Yet, I do like his intentionally goofy stage banter. At one point during his set, a noisy passing aircraft interrupted one of Misty's songs — and he decided to act as if he'd planned the whole thing. "Do you have any idea how much it cost to have a plane fly overhead at that particular moment?" Misty said to the crowd at the song's conclusion. "I'm starting to think it was a bit indulgent."
