"Street Theory 101" is a legendary 1996 underground East Coast hip-hop track by Brooklyn rapper Problem (also known as Problem Child or Problem Solver). It is highly sought after by vinyl collectors and is especially relevant given the borough's rich history in independent 90s rap.

“Everybody knows the Brooklyn-based emcee Skanks The Rap Martyr ... no need to introduce him or talk about all the good work he has done since 2013 with the help of Shinigamie Records and Bankai Fam. Except maybe if you missed this part ... Skanks isn't a new comer ... he has been into the New York Hip-Hop Scene since the early 90's... at that time he was very young and was known under the name of Problem Child. Skanks : "Rampage Da Last Boyscout from Flipmode gave me my name after my first show when I was 11 years old. I even got a write up in Rolling Stone Magazine with Bart Simpson on the cover for that show... Him and Busta Rhymes showed me mad love." His first official appearance was on the "Underground Airplay II" mixtape released by Echo Unlimited in 1994. His track "Gettin' Into Mischief" produced by Self is the first track of the B-side.”

I had plenty of offers on the table after that appearance on the Lyricist lounge Tape, I was having meetings almost every other day but I wasn’t in control of my career being a minor and my mom gave my big bro Goldie permission to handle my business who decided to go the indie rout instead and we released our first single "Street Theory 101" with Beat Street records which eventually sold out all our vinyl. " One year later in 1997, he released an other 12-Inches (Deal's Off / Drug Dealz) under the name of Problem Solver. It featured The Riot Squad and both tracks of the wax were produced by his brother Goldie.
