The Cure are an English alternative rock band, formed in 1976 by Robert Smith, Lawrence Tolhurst and Michael Dempsey. The band has had several changes of membership, with Robert Smith being the only constant fixture throughout the years. In May 1979 their debut album "Three Imaginary Boys" was released to great acclaim, and the band toured extensively to support it. Their sound at this point was placed in the post-punk and New Wave movements, but as through the following years they gradually became darker and more tormented, eventually spearheading the gothic rock genre. After the release of Pornography in 1982, the band had reached the limits of their sound, and an extremely volatile tour led to Robert Smith deciding to change things. He did this by introducing many more pop elements into their sound, and in doing so created many of The Cure's best known and most commercially successful tracks, such as "The Lovecats", "Friday I'm In Love", and "Just Like Heaven". The Cure are still one of the most popular alternative rock bands in the world, and have so far sold over 27 million albums worldwide.
