Query: Oscar Peterson

THis book is a collection of songs that Oscar Peterson approved himself. These transcriptions of classic songs such as "Hymn to Freedom" and "Oscar's boogie" are in it however these transcriptions are for real. They are seriously hard to play because they literally are note for note. Only if you are a seriously good pianist should you get this book. The master of jazz has it hardcore here, no simple stuff. Its the real stuff. On the up side, its magnificent.
