In 2011 he moved to the United States of America in order to pursue his Bachelor’s Degree in Jazz Studies in the genre’s country of origin. During his studies at Western Michigan University (WMU) Lasse worked and performed with noted jazz musicians such as Joe Lovano, the New York Voices, John Clayton, Billy Drewes, Alon Yavnai, Jamey Haddad, Mike Crotty, Billy Hart, Tim Hagans, Peter Eldridge and Fred Hersch, and others. Though many ensembles, and performance opportunities kept him busy, Lasse pursued his academic excellence relentlessly over the course of his collegiate career. He was a member of the Honors Society at WMU, and in his senior year was named Presidential Scholar, an annual award given to one graduating senior based on outstanding academic and artistic accomplishments. Lasse graduated from WMU with highest honors in 2015.
Aside from his studies Lasse gained significant performance experience on various stages across Europe and America. His most memorable performances were as a guest soloist for the South Jutland Symphony Orchestra in Sonderburg, Denmark and as a headliner with WMU’s Gold Company, a vocal jazz ensemble, at the “Les Choralies,” an annual choral festival of 5,000 participants in Vaison la Romaine, France.
