Jasper Shawn Lorelei (born April 18, 1979) is an American singer-songwriter and musician. He is best known as the frontman for the metalcore/melodic death metal hybrid outfit Gaghiel. For the alternative metal band Osmosis, he replaced Adam Guerilla on lead guitar and contributed for nearly thirteen whole years. He also co-wrote a majority of the band's lyrics; prior to his inclusion into the band, vocalist Marco Simmer wrote these independently.
During the spring of 2013, the band had announced that Lorelei departed from Osmosis, although on very good terms. Adam officially returned after he previously "broke the chain". He is now in a side project with one of the band's current members, Corey Farrell.
