I have a large collection of transcriptions, so I wasn't sure the Guitar Play-Along series would be worthwhile for me. As it turns out, this book is a lot of fun to work with, and has actually got me back playing more guitar than I have in a long while.
The general approach of these transcriptions is to provide complete accuracy, but to arrange the songs for one guitar. If you were the lone guitarist in your band, these transcriptions represent the parts you would most likely choose to play. The solos are completely tabbed out, too.
The CD is great. The backing tracks sound amazing, accurately reproducing the parts and tones of all the other instruments. Vocals are omitted, but you get two versions of each song, one with the main (i.e., transcribed) guitar part, and one without it, so you can "play along" (hence, the name). The software that allows you to slow down the song is great, and if used properly, lets you really learn the parts correctly before starting to bring them up to speed.
The mix of songs here is good, providing both some easier songs, and some others you can sink your teeth into. One quirk: I'm not sure why Mississippi Queen by Mountain, a band from New York City (!) is considered a Southern rock song. I mean, it's a great tune and all, but the only thing Southern about it is the mention of Mississippi in the title and lyrics. Several classics by The Allman Brothers and Skynyrd, though, make up for this geographical lapse.
I love this book, and plan to check out other volumes in the Play-Along series.
