I've had this book over two years, and I've had lots of fun working my way through it (as well as jamming with friends). It's packed cover-to-cover not only with Stax and Motown songs, but also a lot of 70s soul and late 1950s rock. Virtually every big hit by Stevie Wonder, the Temptations, and the Supremes are here along with a lot of Otis Redding, Mariah Carey, Whitney Houston and the Jackson 5ive. I've found the arrangements are pretty accurate, and it's a lot cheaper buying the songs this way rather than in some other formats. This would be an ideal book to have if you are in a wedding or party band and are expected to know and play a dozen or so classic R & B songs.
There are a couple of caveats. First - this is fake book format. Fake books give you the chords and leads on a staff, but the rest of the song is up to you. Professional gigging musicians constantly 'fake' arrangements, and this should not be a problem if you are jamming to these songs. Second - Hal Leonard seems to have wanted to cram in as many songs as possible, limiting the songs to just one or two pages. This means the print is small, and will be especially irritating in a dim room. Third - there's no TAB for guitar. Normally I wouldn't complain about that, but when you're dealing with so many songs with tasty guitar parts, a little TAB would have helped.
Still, this is a great treasury of great songs. Anyone who grew up with Motown and Stax and who plays an instrument will love this one. Furthermore, there seems to be less overlap between this book and other Hal Leonard volumes than other collections I've seen, so there's a lot of value for the money.
