Mad, Bad, and Dangerous to Know is the third album by British band Dead or Alive. Several hit singles can be found on this album, including "Brand New Lover" and "Something in My House". The fun and energetic synth-pop and dance album continues where Youthquake ended. The dance-pop songs are little heavy than the HI NRG songs of their earlier records. It's the last record with the original line-up and one that's creative and versatile.

Dead or Alive found success in the mid-1980s and sold over 50 million records worldwide. Founder and vocalist Pete Burns passed away in 2016 and since the band discontinued.
