Foreigner – 4 (1981):  This fourth album by the hard rock band Foreigner took their solid formula to new heights, thanks in part to the efforts of top record producer Robert John “Mutt” Lange, who had just shepherded the milestone AC/DC album, Back in Black (1980).  Nearly all of the songs on 4 are memorable, with a variety of moods; and several were smash hits that still resonate strongly decades later:  “Waiting for a Girl Like You”, “Juke Box Hero”, and “Urgent”, with the latter song featuring saxophone by Junior Walker.
