Query: One of the best albums of the '90s

Sugar is one of the great records of the '90s, in fact its in my personal top ten. The rock songs are instantly catchy and the ballads have a quiet depth lyrically and musically. The overall quality of the songwriting is outstanding. Their previous album was uneven with some rock'n'roll highpoints, 'Sugar' is all quality. The followup to 'Sugar' is 'Head on Straight', while not quite as smooth as 'Sugar' it too is a worthy addition to any rock and roll record collection.
