Query: Essential Guitar

Any guitar player must have this, period. This is one of the first electric guitarist, and yet, this is as good as the electric guitar can get. Charlie Christian is a titan, not only for the guitar but for jazz in general. Be-bop? Just listen to this guy and you'll understand the connection bewteen the old swing jazz and the new thing that was coming. Charlie knew it all along. The alterante takes are also essential, like Bird alternate takes, each one has a different solo and must be heard and compared and studied to get an idea of the genious of this man. The packaging, while beautiful is stupid, you need to take your CDs into jewel cases to prevent damage. But all is forgiven for the amazing sound quality, breathtaking. All stars, five star release!!
