Followers of Danish musician/teacher Birger Sulsbrück (Salsa Na Ma) will be pleased to know that we now carry this in-depth (184 pages) high quality book and 3-cassette package (sold separately) companion to Birger's video. This material, by the way, goes beyond Cuban instruments to include those of Brazil. As you would expect from Mr. Sulsbrück, the different band types and their respective rhythms are clearly explained. Includes photos and text as well as written music. A really nice job. Revised editions.
