Mads Haarløv was the guitarist and vocalist for the Danish death metal band Iniquity.
He returned in 1999, now as lead guitarist and vocalist too, and stayed until the band's split in 2004.
In 2000 Haarløv formed a death metal band with Morten Løwe Sørensen and fellow Iniquity members, Kræn Meier and Martin Rosendahl called Strangler which has released one demo so far, Infinite Blood Abundance in 2004.
The band is still active and have recently acquired the vocal talents of Dave Ingram who also sings for fellow Danish metallers Downlord.
When Mads Haarløv and Jacob Olsen left Iniquity they formed Swollen.
