Ever hear that song at the end of the season-four trailer for Netflix’s “Orange is the New Black”?

The band behind the tune, Kaleo, will give a live sampling of “Way Down We Go” at Firefly in Dover on June 17.

Natives of Iceland, the indie folk-rock/blues group Kaleo are on a mission for world domination, one festival at a time. About a year ago, the crew moved from their homeland to Austin, Texas and played their first U.S. show. A year later, Kaleo sold out their first U.S. headline tour, which began in February.

“Way Down We Go,” Kaleo’s latest single, quickly rose to the Top 10 on alternative radio, having already lit up the Top 10 at prominent outlets nationwide. The song has more than 10 million streams on Spotify.

The gang’s debut album, “A/B,” drops this Friday. In addition to “Way Down We Go,” the project will include popular tracks “No Good” and “All The Pretty Girls.”

As a collective, the guys in Kaleo discussed the origin of their band name and more in this edition of Five Questions, featuring a new interview every day at Doverpost.com until Firefly starts June 16.

For those who may not be fans yet, describe your music in 10 words or less.

It’s soulful, diverse and dynamic.

How did you come up with your name?

We liked the name and the meaning. It means the voice or the sound in Hawaiian. It got stuck very quickly. We were looking for a short name that would also work internationally.

Have you ever been to Delaware? If not, what have you heard about it?

Don’t believe we’ve been yet. All I’ve heard is that it’s one of the smallest states. Definitely not as small as Iceland though.

Who are a few of your favorite artists?

Really too many to mention. Some of them are The Beatles, Ray Charles and Robert Johnson.

What are you doing for summer vacation?

We get a few weeks back home in Iceland in June and July. We’re very-much looking forward to that.
