Caspian loosely formed in Autumn of 2003 in Beverly, Massachusetts,[1] developing material through the first year of its existence, recording a demo in May 2004 and performing a small number of shows in late 2004 and early 2005, including support for the Japanese post-rock band Mono.

In January 2005, the band signed with Dopamine Records, releasing a debut EP, You Are the Conductor in November 2005.

Over the course of 2006, the band developed material for a debut album, recording with Ethan Dussault again in August 2006 in Cambridge, Massachusetts at the newly renovated New Alliance Audio.

Released on Dopamine Records on April 10, 2007, their debut album, The Four Trees, continued their positive exposure to a growing underground of post-Rock fans.

[citation needed] Now officially a 5 piece band, Caspian released a follow-up to their debut called Tertia in Europe on 7 August 2009 and in the US on 15 September 2009.

To tour the album upon its release, Caspian enlisted Washington DC area guitarist, Jonny Ashburn, and Austin, TX bassist, Jon McMahan to assist.

The band played their final concert of 2010 at the Middle East Downstairs in Cambridge as part of the "Last Night on Earth", the eighth of the series, with Constants, Irepress and Moving Mountains.

The album was mixed at Red Room Studios in Seattle by Matt Bayles with the band for 10 days in May, 2012.

Hymn for the Greatest Generation was the final recording on which bassist Chris Friedrich appeared, though it was released after his death.

On June 26, Noisey premiered the first single, "Sad Heart of Mine", off the upcoming record, titled Dust & Disquiet.

[10] On October 20, the band released a short film that was accompanied by a new song, "Castles High, Marble Bright".

The 22 date tour started in Washington DC at the Rock and Roll Hotel and ended on November 19 a Bar Le Ritz, in Montreal, Canada.

On the November 1, 2016 stop of the tour, the band was recorded performing live at the Teragram Ballroom in Los Angeles to be later featured on Last Call with Carson Daly.

The segment aired on November 15 in the U.S. and it featured "Sad Heart of Mine" as well as a shortened version of "Arcs of Command" in the latter part of the program.

Recorded at the same venue, the second airing of the show had an abridged performance of "Castles High, Marble Bright".

The band was part of the "Forever Alone Festival" that took place at Foro Indie Rocks in Mexico City.

The tour opened in Washington D.C. on March 16, and concluded on April 22 when both bands appeared at the New England Metal and Hardcore Festival in Worcester MA.

On April 29, they played the Strawberry Festival in Shanghai and then on May 1, for a headline show at Modern Sky Lab in Beijing.

On 21st, June the band announced the release of "On Circles: The Complete Sessions", a deluxe 2LP limited to 1500 copies and containing three new tracks.

One highlight of their summer will be a headlining appearance at the Post Festival in Indianapolis, Indiana USA in July 2024.

A few days after the tour wrapped up the band headed overseas to perform at the ArcTanGent Festival on 17 August.

The 13 song set ran just shy of 120 minutes and featured the return of former members Joe Vickers, (who played on Loft) and Erin Burke Moran who performed on "Rioseco".

During the set, Calvin Joss performed a solo acoustic piece called "CMF" which is a homage to their friend and former bass player Chris Friedrich who passed away in 2013.
