Most people have probably already heard about this, but it’s still cool enough to be worth a mention: To accompany the release of their best-of compilation, "Scattered Ashes - A Decade of Emperial Wrath," Emperor also released a tablature book of the same name.  The book contains complete guitar and bass tabs for all 13 songs on the first disc of the album, transcribed by Ihsahn himself.  As a bonus, the book also includes the first "Scattered Ashes" disc so that you can play along with the songs.  The song selection include many of Emperor’s most popular tracks, spanning the band’s entire career:

1. Curse All You Men!
2. The Tongue of Fire
3. The Majesty Of The Nightsky
4. Cosmic Keys To My Creations And Times
5. Wrath Of The Tyrant
6. The Loss And Curse Of Reverence
7. An Eley Of Icaros
8. I Am The Black Wizards
9. Thus Spake The Nightspirit
10. Ye Entrancemperium
11. In The Wordless Chamber
12. With Strength I Burn
13. Inno A Satana

The easiest place to get is probably either Amazon, if it’s in stock, or Candlelight Records, but you can also grab it from The End Records/Omega Mailorder or Seattle’s Kreation Records.  Emperor is one of the most innovative and talented bands in metal from a musical composition standpoint, so this book should be an invaluable tool to aspiring metal guitarists everywhere.  Highly recommended.
