Swedish pianist Oscar Micaelsson stopped by the WQED-FM studio to perform piano improvisations in promotion of his July 12th concert at City Theater.  Oscar sat down with Luke Campayno to discuss his career, background, first impressions of Pittsburgh, and more.  His first improvisation turned out to be a gargantuan piano exploration of the opening to Gustav Mahler’s 5th symphony.  He closed the session with a beautiful improvisation on a Swedish folk song that has been used as a hymn.
