LP4 is the fourth studio album by Ratatat, released on June 8, 2010. The name comes from the acronym for long play (LP), as it is their fourth album. It is similarly titled to their third release, LP3. A majority of the tracks are from the same studio session as their previous album.
The album largely features material produced during the session of Ratatat's previous album LP3, recorded at Old Soul Studios in New York.Evan Mast of the duo stated, "A lot of the sounds and palettes are similar, but I think the songs change pretty drastically." Ratatat had purchased several Middle Eastern percussion instruments, which are featured in LP4. The album also features a string quartet, whereas previous Ratatat albums had used a Mellotron. The string sections were recorded at Glassworks Studios in Manhattan. Music videos were produced for the tracks "Drugs", "Mahalo" "Neckbrace", and "Party With Children". The album contains numerous spoken word samples, including a line from Werner Herzog's 1977 film "Stroszek" seguing "Bilar" and "Drugs".
