Alkaline Trio / Hot Water Music is a split EP by the punk rock band based in Chicago, Alkaline Trio, and the punk rock band based in Gainesville, Florida, Hot Water Music, released January 22, 2002, through Jade Tree.
In addition to new material, the EP features each band performing cover versions of songs from the other band's catalog, with Alkaline Trio covering Hot Water Music's "Rooftops" (from No Division) and Hot Water Music covering Alkaline Trio's "Radio" (from Maybe I'll Catch Fire) and "Bleeder" (from I Lied My Face Off).
It was Alkaline Trio's first release with drummer Derek Grant, who replaced previous drummer Mike Felumlee in 2001. Both bands later re released their songs from the EP on compilation albums, with Alkaline Trio's tracks appearing on Remains in 2007, and Hot Water Music's tracks appearing on Till the Wheels Fall Off in 2008.
Critical reception to the EP was positive, with Kevin Hoskins of Allmusic praising "Queen of Pain" and "'God Deciding'" as representative of each band's best material to date, specifically praising George Rebelo's drumming. Jason Thompson of PopMatters praised Alkaline Trio's tracks over Hot Water Music's, preferring Matt Skiba's singing voice to Chuck Ragan's and remarking of the latter that "All too often the vocals are of that saliva drenched, back of the throat variety which takes out a lot of the punch of this group, whose musical abilities are as tight as the Alkaline Trio's."
