New ways to get better results
In 2008 Néstor Crespo begins to make workbooks for his students in his private classes with a concrete and practical way of studying, without an overabundance of text and excellent graphics, to allow the student an optimal approach to different musical aspects for their development.
In this way the 20&20 Series was born.
Now, his books are studied all over the world by self-taught students or professors for their own teaching, and they are also study material in public and private institutions.
Years later, Crespo decides to invite other excellent professors to join in this pedagogic endeavor.
