Born in Normandy, Guillaume Estace moved to Paris in 2001 to study at the American School of Modern Music, where he deepened his expertise in guitar, improvisation, harmony, composition, and orchestration.
After receiving the Pierre Aguiton Scholarship from the General Council of La Manche and a World Scholarship Tour grant from Berklee College of Music, Guillaume relocated to the United States. He graduated Summa Cum Laude from Berklee in 2009. During his time in Boston, he had the privilege of working with some of the most distinguished professors in the U.S., including Mick Goodrick, Tim Miller, and David Gilmore.
Since then, Guillaume has performed and taught across Europe, the United States, Canada, Japan, Ukraine, and England. He has collaborated and toured with notable artists such as Vanessa Paradis, Matthieu Chedid, Ayo, Jane Birkin, Angelo Debarre, Stan Harrison, Gary Georgett, Lulu Gainsbourg, Brad Thomas Ackley, Lawrence Clais, and Magic Malik.
In addition to his performance career, Guillaume is the founder of Guitar-Sessions, alongside Edouard Brenneisen, and serves as the General Manager of the American School of Modern Music.
