Rock Dream is a collaborative live album between Japanese band Boris and Japan noise musician Merzbow.

[1] Thom Jurek of AllMusic noted that the album was nothing like Sun Baked Snow Cave, a previous collaboration between Boris and Merzbow.

[3] The American version had packaging designed by Stephen O'Malley, with their printer stating that they "never ever make anything like this again as it was painfully time-consuming and took forever to get just right!

[3] The Austin Chronicle discussed the album in their overview of Boris' career, declaring it "definitive live document, an impossibly dense double album that touches down on nearly every point of their career, from Dronevil to Smile's contorted stairway to heaven ("Flower Sun Rain"), with Merzbow's electronic manipulations stitching it all together like connective scar tissue.

"[5] In 2008, Raoul Hernandez of the Austin Chronicle placed Rock Dream on his list of top ten albums of 2007.
