These are Volumes 1-4 of the Bad Boy mix tapes that came out in the mid 90's. This was the era when mixtapes were actually mixed on cassette tapes (I still can't use the term "Mix CD"). Before the internet was poppin, this was the place to get exclusive freestyles and all the newest Bad Boy records from BIGGIE, Craig Mack, The Lox, 112 and anything Bad Boy. They also had all the hottest records of the day, not just Bad Boy joints. Add to that they are hosted by Puff Daddy and mixed by the hottest DJs in NYC at the time and these are classics tapes.
