John - if you want a real treat, get your hands on some concert/musiv DVDs. They will blow you away. A few suggestions.

Eagles - Hell Freezes Over
Fleetwood MAC - The Dance
Norah Jones - Live in New Orleans
Diana Krall - Live in Paris

Also, most folks don't consider their libraries. Our county library system has 5000 DVD titles and double that for CDs. They will send from other branches to your branch. Great opportunity to try out a wide range before buying. You can likely get into the library catalog on-line.
Eric Clapton - Live at Hyde Park.
