Wow and Flutter is an EP by the post-rock band Stereolab, which served as the second single from their 1994 album Mars Audiac Quintet. A limited edition of 3,000 7" copies was released with hand-painted covers. The EP was also released on CD and 10" vinyl.
Two of the tracks are alternative versions of songs on Mars Audiac Quintet. "Wow and Flutter" itself is a re-recording, while "Nihilist Assault Group, Pts. 3-5" comprises sections excised from the album version, which was originally planned to be a side-long suite similar in concept to the 18-minute "Jenny Ondioline" on Transient Random-Noise Bursts with Announcements.
All tracks appear on the Oscillons from the Anti-Sun 2005 compilation album.
