Sean Imboden | "Uncharted Realms"

Indianapolis’ Acclaimed Sean Imboden Large Ensemble Returns with its Vibrant Second Album

Uncharted Realms Finds the Big Band Exploring

New Sonic Terrain

“Imboden’s contemporary vision unfolds with clarity and creativity, reflecting a composer who understands how to draw the best from his ensemble. Uncharted Realms is another ambitious and cohesive musical statement.” — Jazz Trail

Indianapolis-based saxophonist, composer and bandleader Sean Imboden remembers the 2017 debut of his Large Ensemble as a less than auspicious occasion – an outdoor gig at a mud-sodden park in front of a “crowd” of roughly a dozen onlookers. There’s only one direction to go from there, but the big band has soared to impressive heights regardless of their humble beginnings.

The ensemble’s first album, 2025’s Communal Heart, met with widespread acclaim, including a 4-star All About Jazz review that hailed Imboden’s writing as, “contemporary big band composition at a high level, liberating form and harmony from prior constraints while still approachable and enjoyable for all by way of his fluidity of phrase and natural gift for creating a melody that will leave you humming for days.”

Imboden has no intention of stopping there. His goals are signaled by the title of the band’s dazzling new follow-up, Uncharted Realms. The album is a scintillating evolution of the composer’s kaleidoscopic music and his tight-knit band’s fervent dedication to expanding the boundaries of the modern big band.

“I never want the band to stay in its comfort zone, or in traditional jazz waters,” Imboden says. “I always aspire to break new ground, leaving the music open to all of the influences I’ve taken in. I let the music go wherever it wants to go, following that direction through all of its twists and turns, holding on and enjoying the ride.”

That process is brought to life via the album’s opening track, “Flowing Currents.” Originally written for a small group, the piece is given bold new life by the Large Ensemble. Imboden’s music traces the unrelenting flow of a body of water, which maintains its momentum despite the presence of rocks in its path, unsteady terrain or forking branches. Like so much of Imboden’s music, the composition has a direct meaning and a more metaphorical one, suggesting the persistence that can carry one through life’s challenges.

“Follow the Kite,” which closes Uncharted Realms, similarly follows a circuitous and unpredictable path, this time capturing the carefree joy of a child racing after a kite, blown about by buffeting winds and waving hills. “Balcony” offers a shift in perspective, its dawning, accruing colors the result of finding a new, loftier vantage point from which to view the world. “When You Look Beyond” gazes even further, past the familiar to look into the uncertain future. The music is the album’s most eclectic, progressing from a lyrical melody to a march beat that gains in power, massing the horns for a soli section that draws from the composer’s love of classical masters like Mahler and Shostakovich – then erupting into a heavy metal-inspired explosion with a blistering guitar solo from Joel Tucker.

As Imboden implies, he rarely writes to a plan, instead allowing the music of the Sean Imboden Large Ensemble (SILE) unfold as his imagination allows. The band’s music nonetheless follows a vivid narrative path, revealing the composer’s strong narrative and expressionist instincts. Take the album’s second track, “The Gentle Giant,” which takes its title from the nickname that a local bandleader bestowed on Imboden – a reference to both the saxophonist’s height and his introspective nature. But it’s also an apt fit for the piece’s storybook aspects: it begins with a thundering, booming force that depicts the titular giant as a titanic menace wreaking havoc on the countryside; the turmoil gives way to a hushed middle section representing a moment of self-reflection, leading to the jubilant finale suggesting peace between the monster and his former victims.

That story’s happy ending, expanded to fit our real-life society, lends another meaning to Uncharted Realms. Though the album is never explicitly political, its pieces do reiterate a hope for the future as we all navigate our uncertain times. “I couldn’t help but think about the discord and strife that we have within our country these days,” Imboden explains. “It left me wondering what things could be like if we look beyond this point. I’m not dreaming of a utopia, but I do hope we can move towards a more idealistic situation. And hopefully we can get there through peaceful means.”

Imboden finds a source of serenity and hope in the natural world, captured not just in the lush, wide-open sensations evoked by his music but in the artwork he selects for his releases. Uncharted Realms, like its predecessor, features a delicate painting by the artist Kara Tucker, whose vibrant bluebird in a muted, wintry landscape suggests rebirth and freedom, the bird’s ability to fly away at will suggesting an escape to new horizons.

Tucker is also the wife of SILE bassist Nick Tucker, which reiterates a theme that was central to Communal Heart and remains foundational to Imboden and his band: the idea of community, both within the band and throughout the larger support system that sustains it. “I’ve worked hard to develop the rapport and camaraderie within the band,” he says. “At this point, it feels almost like a family reunion whenever we get together. Our audience has developed at the same time – we have dedicated fans who have followed us since that first gig back in 2017, and it has continued to grow from there.”

Word is spreading beyond Indianapolis as well; along with the positive reaction to the band’s first album, a number of special guests have added their voices to the ensemble in recent years, including trumpeter Mike Rodriguez, pianist Taylor Eigsti and trombonist Ryan Keberle. Imboden is striving to take the band to festivals and bandstands across the country in the wake of the release of Uncharted Realms.
