Solid Base was a Swedish-Norwegian Eurodance group.

The lead singer in the group was Isabelle Heitmann, who was born in Oslo, Norway in 1972. She had a passion for singing since her childhood, and at the age of 10 she moved to Gothenburg, Sweden. A few years after she had moved to Stockholm, she started to sing in various talent competitions. One day she got a phone call from producer Pat Reiniz asking her to sing for him. She ended up singing for Cool James and Black Teacher on their album. At work she met a man named Niclas Lindberg who recommended her for the Solid Base project.
