Twenty One Pilots build an army for a revolution against a tyrannical cult in the music video for "Nico and the Niners."

A few weeks after they had finally ended their year-long hiatus, the rock/hip-hop duo dropped the second single out of their upcoming album. The new music video, directed by Andrew Donoho, is a follow-up to "Jumpsuit" that was released earlier this month.

Twenty One Pilots Is Ready For A Revolution

After an encounter with the mysterious hooded figure in a valley in "Jumpsuits," the action continues in "Nico and the Niners." The music video opens with lead singer Tyler Joseph inside his room plotting his escape from the city.

Meanwhile, underground, an army led by Josh Dun has started to stir. The men and women, who wore the same jumpsuits in the first music video, unite and eventually take to the streets with their torches as people look out from their windows.

The rebel group encounters Joseph and Dun hands him a microphone. He starts to rap and sing, disrupting the silence of the neighborhood. By the time the creepy hooded men catch a whiff of the impending revolution, Joseph, Dun, and the rest of the rebels have escaped.

"East is up, I'm fearless when I hear this on the low/ East is up, I'm careless when I wear my rebel clothes," he sings in the hook. "East is up, when Bishops come together they will know that/ Dema don't control us, Dema don't control/ East is up."

Immortal Reviews suggests that the events in the music video for "Nico and the Niners" might have taken place before "Jumpsuit."

The 'Trench' Lore

The music video expands the lore that Twenty One Pilots has been building in the past couple of months. The mention of Dema recalls a mysterious website, which fans found a couple of weeks ago detailing a city ruled by a tyrannical group. The website has since been deleted.

"East is up" is a phrase that also floated around Twitter and Tumblr fan pages. It first popped up from the same website that had come out and had been deleted before "Nico and the Niners" was released.

Clues on the lore that was created by Joseph and Dun for their new album have remained scarce. However, fans can likely expect more information as the duo reveals the next chapter of the story in the third music video.

Trench, the follow-up to Blurryface, is set for release on Oct. 5 via Fueled By Ramen. Twenty One Pilots is also set to kick off their tour on Oct. 6 in Nashville.
