Praised as the “Rampal from Brasilia” by Maestro and composer Júlio Medaglia (Preludio TV Show, 2014) for his powerful sound, refined technique and artistry, Andreas has become one of the most prominent flutists of his generation.

Brazilian flutist Guilherme Andreas received First Place in the 2020 International Music Competition "Paris and London" Grand Prize Virtuoso and 2019 Concert Artists International Virtuoso Competition’s professional division. 

Andreas began his musical career in Brazil, where he studied at the University of Brasília and then completed his Bachelor’s Degree in Flute Performance at the Brazilian Conservatory of Music, under the guidance of French Professor Odette Ernest Dias. Andreas also received a Graduate Diploma in Chamber Music at the same institution being mentored by British cellist Sr. David Chew, and studied in parallel with Cláudia Ribeiro do Nascimento (OSESP) and Michel Bellavance (Conservatoire de Genève). 

As a soloist of the Brazilian Marines Wind Symphony, Andreas performed in major concert halls throughout Brazil and other countries of South America. As a chamber musician, his concerts with Trio Gaubert (cello, flute and piano), took place in theaters and museums throughout Rio de Janeiro. Andreas received numerous prizes at competitions in Brazil including Young Soloists of the Eleazar de Carvalho Festival and the Sargent Borges Medal, granted to the leader of the Sergeant Musicians Course of the Brazilian Marine Corps. He also received a full scholarship to pursue his Masters studies in flute in the USA, awarded in Brazil by the Young Musicians in the Museum Competition in partnership with James Madison University in Virginia. 

During his Master’s studies, Andreas won the JMU Concert Competition, culminating in a performance of the Reinecke concerto with the JMU Orchestra. In 2016, Andreas began studying at the Peabody Institute of the Johns Hopkins University, where he received his Graduate Performance Diploma, and the Peabody Career Award in 2018. A highpoint of his time at Peabody was his performance of the Nielsen Flute Concerto with the Peabody Symphony Orchestra.

Andreas has appeared in recitals, concerts and presentations throughout the US, including the Global Brazil Conference at Duke University, Symposium on Brazil at Johns Hopkins University, and recent concerts in Nashville, Washington, New York City, Rochester, Boston, Seattle, among other cities. After being invited to perform as Principal Flute with the New England Symphonic Ensemble at Carnegie Hall in NYC (2016-2019), Andreas gave a solo performance in 2019 together with fellow CAI Virtuoso Competition winners. 

Andreas was also appointed as a Trevor James Alto Flutes Artist, selected to be a member of the 2019 Global Leaders Program, and awarded the SphinxConnect 2019 and 2020 Fellowship and a 2020 Sphinx Orchestral Partners Auditions Fellowship. Andreas is also an Artist in Residence with Sugar Hill Chamber Music series. 

Andreas has been an active performer throughout the U-S, and his debut album Beyond Bossa Nova has been received with great acclaim to all audiences in the US and other countries. His most recent performances include guest appearances with the Seattle Symphony Orchestra, Lincoln Center's Mostly Mozart Festival with The Unsung Collective and the Kennedy Center Honors Concert Orchestra.

Andreas is currently based in New York, where he dedicates his time to performing, teaching, and discovering historically lesser-known composers, whose works express extreme ranges of emotions and demand tremendous virtuosity.
