Marcelo Barbosa (born in 1975) is a Brazilian guitar player and music professor. He is a founder or member of a few important Brazilian bands like progressive metal act Khallice and former Angra vocalist Edu Falaschi's band Almah. He also is a founder and an owner of a large musical institute in his home city Brasília called GTR, a columnist of the Cover Guitarra, Guitar Class and Guitar Player magazines and an Expo Music (Brazil) and NAMM (US) musical exhibitions participant. Endorser of Tagima guitars. Since September 2015, he is also Angra's touring guitarist replacing Kiko Loureiro, who is now a member of Megadeth.
Marcelo Barbosa began playing electric guitar when he was 11 years old. He was studying with several teachers, mainly with Allan Marshall. At 17 years old he already was a professional musician and a musical teacher in two musical schools in his home city Brasília. He then decided to establish his own one, focused on the electric guitar. Besides organizing work and managing other teachers, Barbosa established his own entire approach instead of copying or adapting any already existed one and he wrote all the didactic material.
Marcelo also attended classes and workshops of musicians like Greg Howe, Lula Galvão, Hélio Delmiro, Toninho Horta, Guinga, Ian Guest among others. In 2002 he finished summer courses in the famous Berklee College of Music. As a result he was chosen with other 11 students to receive a scholarship for the college's regular course. However, it was not possible to continue due to GTR and his other responsibilities.
Some time before that Marcelo became a member of Brasília pop rock band Zero10. They released an EP and a full-length album Novo Dia and they play almost every week at different venues of the capital of Brazil. Later on, he would restart the band Khallice, which played the progressive metal he always liked.
