If drummer and multi-instrumentalist Jack Irons were an actor, he’s probably be Harrison Ford. While Ford is known for starring in two of the biggest movie franchises of all time — Star Wars and Raiders of the Lost Ark — Irons played integral roles in two of the highest-profile rock bands ever: Red Hot Chili Peppers and Pearl Jam.

Just as those two monstrously successful groups keep making albums and playing concerts decades after they became famous, Irons continues to endure as well, albeit much further under the radar. As the Chili Peppers’ founding drummer and a key player on Pearl Jam’s ’90s albums, Irons is now expanding his repertoire with his fourth release as a solo artist.

This time around, the Rock and Roll Hall of Famer isn’t putting out a conventional solo record. Instead, on March 4, he will issue a 12-inch vinyl release that binds together his brand-new Koi Fish in Space EP with his 2019 EP, Dream of Luminous Blue. The so-called double-EP, released by Org Music, features Koi Fish on Side A and Dream of Luminous Blue on the flip side.

Today, the Big Takeover exclusively premieres the first taste of Koi Fish,: a stream of leadoff track “Passing Through.”

The double-EP contains a total of 12 songs, including many that revolve around space as a theme: “In Orbit,” “The Moon,” “Saturn” and “Cosmic Planes.” But it’s “Passing Through” that Irons and Org Music are pushing as a single.

Take a gander of the song right here:

Irons spoke exclusively with the Big Takeover about the track, explaining that “Passing Through” isn’t about a musician who plays from one band to the next. (Irons also previously recorded and toured with Neil Young, Joe Strummer, Les Claypool, the Wallflowers and many groups.) Rather, the new song captures Irons’ existential thoughts.

“A note about ‘Passing Through’ … from the author (haha),” Irons said. “I have been trying to figure where the original groove inspiration came from [but] I can’t recall. My process [involves me] playing to an inspiring tune or groove, recording myself, then creating new sounds with [the previous] sounds and adding some keypads for a bit of melody. I lean on atmospheric qualities and, to me, it sounds like being an observer or just ‘Passing Through’ this life for at least three minutes or so …”
