Playalong Books

While picking up a new felt for my cymbal yesterday I discovered that there actually are TWO series of playalong drum books...the Hal Leonard series AND the Alfred series. I actually have one Alfred book (Green Day) and just didn't realize, because the cover art and format are so similiar, that it was a different company. So yesterday I picked up Alfred's Rush book (more on Rush in a minute). Thankfully there aren't many Alfred books in the series(and I don't recognize many of the drummers)...or I'd go broke. I seem compelled to collect all these things.
