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 is the second in a series of experimental and mostly instrumental releases put out on the band's own SYR label.
SYR2 follows 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 vinyl pressings accidentally being on black. 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) appears on the group's 1998 album A Thousand Leaves as the song "The Ineffable Me". Additionally, a melody from "Stil" was fleshed into the song "Snare, Girl", also from A Thousand Leaves.
