While rumors of an Oysterhead reunion had been percolating for months, excitement spiked last Monday night when new accounts for the band appeared on Instagram and Twitter. The accounts each made a single post: a soundless typewriter animation spelling out a few words over a muted pastel backdrop: “when all else has been done and said.”

Fans of Oysterhead quickly recognized the lyrics from “Mr. Oysterhead”, which appeared on the band’s only album, 2001’s The Grand Pecking Order: “When all else has been done and said… along comes Mr. Oysterhead.” The following day, the band officially announced their reunion run in Colorado.

The trio first came together on May 4th, 2000 for a late-night performance in New Orleans during Jazz Fest at the Saenger Theatre. In 2001, due to overwhelming demand, the trio reformed to record and release The Grand Pecking Order, which featured nine new tracks in addition to four songs debuted at the Saenger. A North American tour followed the release of the album.

On June 16th, 2006, the band reunited for a set at Bonnaroo. The three scheduled Oysterhead reunion shows will mark their first live performances since that Bonnaroo set nearly 13 years ago.
