Shugo Tokumaru has spent nearly a decade refining his whirlwind indie-pop, a combination of precise guitar playing and a nursery-schools-worth of toy instruments and other oddball musical knick-knacks. His hard work has paid off – he’s seen higher record sales over the past three years, peaking with last year’s well-rounded “In Focus?” His afternoon set at the Field Of Heaven wasn’t a victory lap as much as it was an opportunity to show off all his Shugo-ness…as he’s been doing since 2004.

Tokumaru has slow songs in his collection – he played one of them, the melancholy “Linne” – but this was Fuji Rock 2013, so he opted to showcase his tumbling pop songs. He opened with the zig-zagging “Katachi,” and along the way played the joyous “Lahaha” (name says it all) along with the song that helped get him more exposure in the first place, the barreling “Rum Hee.” Live, he allowed the songs to explore new sides of themselves – Tokumarue and his band were jammier than usual, and weren’t afraid to try out new, silly sounds while exploring these tracks. Other times, he stuck to the template of the original, like on the guitar-precision-workout “Parachute,” one of the most well received songs of the afternoon.

The crowd enjoyed it, even when the sky started pouring out rain near the end of his set. In a bit of odd timing, he was playing 2012 track “Down Down” when the rain was coming, errrrr, down. Yet Tokumaru’s joyful music made a fair amount of people simply dance during the deluge, rather than seek shelter. Just Shugo being Shugo.
