Soho was the prominent art arena and Pehrson joined Noho Gallery on Mercer Street in 1994 and had several shows both there and at other places around the downtown art scene.
Three years later, Pehrson spent four months in Barcelona, Spain. He worked with local artists and painted on a daily basis, greatly inspired by Catalan art.
Upon return to New York, Pehrson had a show at the Noho Gallery where he exhibited work that reflected the Spanish influences. He was also fortunate enough to find a studio on Beaver Street in Lower Manhattan. In a small building that houses an Irish bar and restaurant, his studio is almost invisible in comparison to the skyscrapers of the Financial District.
The effects of 9/11 on New York City, and more specifically Wall Street, strongly influenced Pehrson’s work. He captured the emotions of the area in a series of 35 monoprints on watercolor paper. This resulted in a traveling show produced by Pehrson in 2003, exhibited in Stockholm, Sweden at the Gallery Wallmark and at the Swedish Consulate in New York City.
The following years until present time resulted in a string of successful shows.
He is represented in institutions and private collections in both Europe and the United States.
Exhibitions include Katonah Museum, NY; Volta Art Fair, NY, NY; Vida Museum, Sweden; Kulturhuset/Stadsteatern, Stockholm, Sweden.
