Sub Pop Records celebrated its 20th anniversary this year, and the local record label commemorated the occasion with a comedy show at the Moore Theatre and a two-day festival at Marymoor Park.

Comedians David Cross, Patton Oswalt, Eugene Mirman and Todd Barry performed at the Moore, while bands such as Flight of the Conchords, Mudhoney and Iron and Wine performed at the festival for free, with profits donated to various organizations.

The weather was almost unbearably hot and not a cloud was seen. Some attendees lounged beneath the trees while others slathered on sunscreen, sunbathing on the grassy knolls surrounding the stages.

Alternating bands played on the larger “This Stage” and the smaller “That Stage,” which allowed audiences to avoid shifting too much and picking between bands.

To kick off the first day, the Constantines played a Rolling Stones cover along with songs from their Sub Pop album Shine a Light.

With a Death Cab for Cutie sound, Helio Sequence proved a noticeable change in vibe. The band caught the attention of many attendees with its mellower indie rock. The band’s use of the harmonica added to the folk festival feel, and each song was distinct. For the daughter of another band, the group played “Blood Bleeds,” a song it has not performed in two years.

Next on That Stage was Pissed Jeans, an alternative punk band that many did not seem ready for after Helio Sequence’s calming effect.

“If it was really late at night and you were in a crowded dive bar and on heroin, this would be great, but in the afternoon at a festival show, not so much,” festival attendee Julian Gerhart said.

The band dedicated its last five minutes to Princess Diana before delving into the final high-energy set.

Fleet Foxes was the complete opposite of Pissed Jeans and continued the chill feel of Helio Sequence on This Stage. It proved to be one of the favorites of the day, starting off with harmonizing a cappella that left many in an awestruck daze. Fllet Foxes’ CD would be the one to buy among Saturday’s bands. Its 40-minute set felt too short.

Mudhoney, the last band to perform on That Stage and one of the bands that helped launch the Seattle grunge scene, turned up the volume full blast and rocked out.

Sam Beam, under the stage and recording name Iron and Wine, was a professor at the University of Miami until Sub Pop got a hold of some of his songs. The crowd was succumbed into silence by his unique voice and impressive guitar skills. One audience member claimed to have had sex to his song, which amused Beam greatly. He teased the audience when he forgot one of his own songs, joking that they were making him nervous, and he had to come back to it later.

Flight of the Conchords, which calls itself “formerly New Zealand’s fourth-most popular guitar-based, digi-bongo, a capella-rap-funk comedy folk duo,” was a perfect end to the first day of Sub Pop’s 20th Anniversary show.

The highlight of the set came when an audience member threw his boxers on stage, which was a first for the New Zealand duo. Flight of the Conchords member Jermaine Clement seemed especially frightened and went to show the audience the boxers; despite lamenting that he did not want to, he held them up and cried out, “Oh, they’re still warm!”

One of the band members commented on the fact that someone in the middle of the crowd was able to take off his boxers, and he sarcastically remarked that the band had actually sent its manager to do so. The group ended with “Business Time” and did not come back for an encore, to the surprise of the crowd.

On Sunday, artists Green River, Beachwood Sparks and Wolf Parade headlined the festival. Wolf Parade performed in promotion of its new album released last month, At Mount Zoomer.

Artists Kinski and Grand Archives represented local indie rock, and six other rock bands also performed.
