Duke marked the first time that Phil Collins seemed to be a major influence in the songwriting process for Genesis. While I'm certain he played an important part in previous albums, Duke introduces us to the drum box with "Duchess", album production that seems to place more emphasis on the overall drum sound, and songs like "Please Don't Ask" and "Misunderstanding" that could have easily fit on an early Phil Collins solo album (it was after all written during the period of Face Value, his first solo project). Not to say that Tony Banks and Mike Rutherford weren't an important part of what made the Duke album a success.
Duke offered audiences the group's first "radio friendly" pop album with countless catchy tunes ranging from "Turn It On Again", "Man of Our Times" and "Behind The Lines" to ballads like "Alone Tonight" and superb instrumentals like "Duke's Travels" and "Duke's End." The album was my first exposure to Genesis (at the tender age of nine), and it left me wanting more. In fact, to this day, I still rank Duke among my favorite albums of all time.
