The Beak Brackets was a series of experimental tapes made by the musical project / concept band Mujeres Encinta from 1999 to 2001.
In this series Mujeres Encinta applied the n+7 principle to some records and songs from The Beach Boys.
According to fan websites [2] these tapes are impossible to find and even-though their details can be found in Discogs or Last.fm little has been written about what they actually sounded like.
[citation needed] Surfeit's Up was released in 1999 and took as its source Surf's Up and the following songs from it: A Day in the Life of a Tree, Don't Go Near the Water and Take a Load Off Your Feet.
They proposed the series to the label who declined, finding the experiment a bit odd for a wider audience.
