Drummers Jacky Bourbasquet (founder of the Sonor school network) and Claude Gastaldin (professor at the Geneva Conservatoire) have a “long and faithful friendship” that goes beyond playing music. Since 1997 the two percussionists have pursued a large-scale educational adventure that earned its fame under the name Drum Session.   Offered in a multilingual version (French English German Spanish) the 17th Volume includes everything that brought the series its success: a progress­ive structure divided into levels clear method instructions and a range of pieces – 29 in total– showcasing a wide variety of styles: jazz progressive pop tango and funk.    The method which favours group work with orchestra is enhanced with a CD (sold separately) in which each piece is recorded without the drums in two versions: one as an étude (slower) the other a tempo. A variety of tracks have been added for a total of 70 minutes of music. “A very useful tool well-designed and including enough styles to satisfy nearly everyone” (Batteur magazine).   This book must be purchased with the CD accompaniment (AL30675) separately.
