For fans of indie rock, Neutral Milk Hotel remains one of the most legendary and mysterious bands of the 1990s. Their 1998 album, In the Aeroplane Over the Sea, is often hailed as one of the greatest albums of all time. While frontman Jeff Mangum is the most recognized name from the band, another key member, Julian Koster, played a crucial role in crafting its unique and haunting sound.
Who is Julian Koster?
Julian Koster is a multi-instrumentalist and songwriter known for his work in Neutral Milk Hotel and his own musical project, The Music Tapes. Born in 1972, Koster grew up with a passion for experimental sounds and storytelling, which later became central to his music career. His contributions to Neutral Milk Hotel went far beyond just playing instruments—his creative ideas and distinctive approach helped shape the band’s signature style.
Koster’s Role in Neutral Milk Hotel
Koster joined Neutral Milk Hotel in the mid-1990s, just before the band recorded In the Aeroplane Over the Sea. He played several instruments, including the saw, banjo, and accordion, giving the album its surreal and nostalgic atmosphere. His use of the singing saw—a musical saw that produces ghostly, high-pitched notes—became one of the most recognizable elements of the band’s sound.
In addition to his instrumental contributions, Koster was also deeply involved in the band’s creative direction. His background in surreal storytelling and avant-garde music influenced the overall aesthetic of In the Aeroplane Over the Sea. The album’s mix of folk, psychedelic rock, and experimental elements reflected not just Mangum’s vision but also Koster’s artistic sensibilities.
The Mystery of Neutral Milk Hotel’s Disappearance
Despite the critical acclaim of In the Aeroplane Over the Sea, Neutral Milk Hotel disbanded shortly after its release. The sudden disappearance of Jeff Mangum from the public eye added to the band’s mystique, and Koster, too, moved on to other projects. However, unlike Mangum, who avoided the spotlight for years, Koster remained active in the indie music scene.
The Music Tapes and Koster’s Solo Work

Following Neutral Milk Hotel’s hiatus, Koster focused on his own band, The Music Tapes. The project combined whimsical storytelling with lo-fi and orchestral sounds, often featuring unusual instruments and theatrical performances. Albums like First Imaginary Symphony for Nomad and Mary’s Voice showcased his unique approach to music, blending nostalgia with surrealism.
Koster’s performances with The Music Tapes were more than just concerts—they were immersive experiences. He would often tell stories, involve the audience, and create a dreamlike atmosphere with vintage recording equipment and homemade instruments. This creative approach made his shows feel like stepping into a different world, much like the music of Neutral Milk Hotel.
Neutral Milk Hotel’s Reunion and Legacy
In 2013, Neutral Milk Hotel shocked fans by announcing a reunion tour. Koster rejoined the band for the tour, playing his signature instruments and helping recreate the magic of their classic album on stage. The reunion tour lasted until 2015, after which the band once again went on hiatus.
Despite their limited discography, Neutral Milk Hotel’s influence on indie music remains immense. Bands like Arcade Fire, The Decemberists, and Beirut have cited them as a major inspiration. Koster’s contributions, particularly his use of unconventional instruments and his experimental approach to sound, have left a lasting mark on the genre.
Where is Julian Koster Now?
Today, Koster continues to work on new music and creative projects. While he remains somewhat under the radar compared to other musicians from the indie rock scene, his influence can still be felt. He has participated in various Elephant 6 projects, a collective of musicians that played a key role in shaping indie rock in the 1990s.
Koster has also continued making music with The Music Tapes, releasing new material and occasionally performing live. His passion for blending music and storytelling remains as strong as ever, proving that his artistic journey is far from over.
Why Julian Koster Deserves More Recognition
While Neutral Milk Hotel’s legacy is often associated with Jeff Mangum, Julian Koster’s role in the band was just as vital. His unique musicianship, experimental spirit, and willingness to push creative boundaries helped define the band’s sound. Without Koster’s contributions, In the Aeroplane Over the Sea might not have had the same dreamlike and haunting quality that has captivated listeners for decades.
For those who love Neutral Milk Hotel’s music, exploring Koster’s work with The Music Tapes and other projects can be a rewarding experience. His ability to create magical and immersive musical worlds continues to inspire new generations of musicians and fans alike.
Though he may not be the most famous name in indie rock, Julian Koster remains one of its most intriguing and imaginative figures. His work proves that sometimes, the most influential artists are the ones who don’t seek the spotlight but instead focus on creating something truly special.
