Query: INCREDIBLE ROCK ALBUM

REO Speedwagon's Nine Lives is without a doubt one of thier best offerings. From the opening rocker "Heavy On Your Love" to the slick "Back On The Road Again" this album really rocks throughout. Nine Lives was released in 1979 before REO turned to a more radio-friendly softer sound. Gary Richrath shines on this album. His absolutely INCREDIBLE guitar playing is very prevalent on EVERY track!! Kevin Cronin's vocals have never sounded better than on Nine Lives. Bruce Hall does lead vocals on "Back On The Road Again"- a very nice addition.As I stated before- Nine Lives REALLY ROCKS!! I love the remake of "Rock N' Roll Music." Also check out how "Meet Me On the Mountain" segues into "Back On The Road Again." Another thing that is different on Nine Lives than most other REO Speedwagon albums- there are no ballads.
