No other artist has more official unreleased Timbaland tracks than Sarah Jo Martin with 9 to date:
-I Can't Stand The Rain
-I'm In Hot Water
-I'm Your Slave
-I'm About To Lose It
-Put The Gun Down
So who exactly is Ms. Martin? More currently known as the former fiance of Backstreet Boys AJ McLean, seems she was around back in Da Bassment days and worked with both Timbo and Missy on a debut album. Though she enjoyed working with both of them and the music came out "incredible", the album had a heavy rock theme that just wasn't Sarah. Eventually the album was shelved, their relationship soured, and they parted ways.
Years later, audio from an interview with Sarah Jo Martin surfaced explaining her relationship with Timbaland and Missy and explaining what really happened, saying Missy was "hardcore, schizo, girl power." (lol) I would love to get my hands on that audio. Sadly this is just another case of a good relationship gone bad and the great music suffering by staying on the shelf.
Get at me if you ever come across info on Sarah Jo, I'd love to get my hands on some of the music she created back then.
