Foxboro Hot Tubs is the garage rock side project of Green Day, formed in 2007.

When performing as Foxboro Hot Tubs, Billie Joe Armstrong and Jason White go by the names Reverend Strychnine Twitch and Frosco Lee respectively.

[7] Although the band's history is, as yet, unknown, they comprise the official and backing members of Green Day (with the exception of Preston), who are performing "garage" music under a nom de plume.

On December 8, 2007, the Green Day site released six tracks, via streaming and downloadable MP3 formats, free of charge to the listener.

The MP3s were reinstated on December 16, but were again removed and replaced with the clock; later the website was changed to simply redirect to the band's Myspace.

[11][12] On October 26, 2013, The Foxboro Hot Tubs played a secret show at Eli's Mile High Club in Oakland, California.

As the Coverups, the band performed a few Foxboro Hot Tubs songs on December 6, 2019, at a small show at the Tiki Bar in Costa Mesa, California.
