Both clips include some animation of an underwater shellfish releasing air bubbles, which may point toward the as-yet-untitled album’s cover art or name.

Back in November, the band revealed that the new album is slated for “early 2019” though fans have yet to be clued in on the release date or album title. Their fourth studio effort will follow up 2016’s Let Me Get By, 2013’s Made Up Mind, and their 2011 debut album, Revelator.

It’s been a difficult month for Tedeschi Trucks Band, as longtime member and keyboardist Kofi Burbridge returned to the hospital last week to undergo another procedure related to his 2017 heart surgery.

The week prior, Tedeschi Trucks Band announced that they will be moving on in 2019 without longtime bassist Tim Lefebvre as he focuses on a number of other musical projects. He will be replaced at the band’s upcoming January and February dates by bassist Brandon Boone, but a permanent replacement has not yet been announced.
