I finally found that CN31109220,took sifting through about 40 tunes this blighter.The sleeve has wrote on it Q.D.T. presents The Cool Tip EP.The cat no. is QDT 001.Its a diverse four tracker and the others are not hardcore.There's 1 belter on the other side,which uses the 'got to be free' vocal from Bassheads-who can make you feel good.The other 2 are quality too,if a little different.
