SYR2: Slaapkamers met slagroom is an EP by American alternative rock band Sonic Youth. It was released on 12" vinyl on September 2, 1997, and was the second in a series of experimental and mostly instrumental releases issued on the band's own SYR label.
SYR2 followed the band's tradition of having the liner notes of SYR releases written in foreign languages, in this case, Dutch. "Slaapkamers met slagroom" is Dutch for "bedrooms with whipped cream".
An error in the original production of the vinyl resulted in a small number of the initial pressings accidentally being on black vinyl. It is unknown how many of these were produced. After realizing this, the remaining production of the vinyl version were on clear blue vinyl. 
An abbreviated version of the instrumental 17-minute title composition (with added vocals courtesy of Kim Gordon) appeared on the group's 1998 album A Thousand Leaves as the song "The Ineffable Me". Additionally, a melody from "Stil" was fleshed out to create the song "Snare, Girl", also from A Thousand Leaves.
