One encore is expected at most concerts.

Second encores are fairly typical, too.

If you’re really lucky, the band may reappear a third time for a cover tune or two.

But four encores? Not likely.

As Hawaii-native singer/ songwriter Jack Johnson exited the stage after his third encore, it was clear the sold-out Maintenance Shop crowd wasn’t going to let him go that easily. It was only after Johnson finished his fourth encore – a cover of The Beatles’ “Rocky Raccoon” – that grateful fans finally let him leave in peace.

The entire hour-and-a-half show took on this appreciative aura. It was perhaps one of the most affectionate crowds the M-Shop has seen in a long time. Before Johnson could even say, “I’m Jack Johnson. Thank you,” after the first song, the crowd was thanking him. More than one person yelled, “Thanks for coming, Jack,” or “Thank you so much, Jack.”

Johnson and his backup band, which consisted of a bass player and a drummer/percussionist, played nine songs from Johnson’s first – and only – record, “Brushfire Fairytales.” Other songs were a collection of covers (Bo Diddley’s “Who Do You Love?”) and soundtrack tunes from the various surf films Johnson has directed.

Most like “F-Stop Blues” and “Posters” were groovelicious slow jams, bolstered by rhythm-laden acoustic guitar style and thick bass lines. Try mixing Bob Marley, Dave Matthew, and Phish and you might get a hint of Johnson’s style.

But the show wasn’t comprised only of hippie singalongs. In fact, it was during the more up-tempo tunes, such as “Bubble Toes” and the title track “Brushfire Fairytales,” that Johnson seemed to shine.

Even the M-Shop itself felt more like a palmy cabana than a central Iowa concert venue in mid-October, as Johnson painted his aural pictures of Hawaiian seascapes and island beaches.

The Mason Jennings Band opened the show. Similar to Johnson’s group, it was an acoustic guitar-led trio. But where Johnson’s vocal delivery had more of a Ben Harper flavor, Jennings’ was more Bob Dylan-ish.

The two styles went well together, though, as Jennings joined Johnson on stage for two songs during Johnson’s third encore.
