In 1974, Sweet, one of the leading glam rock bands, underwent its first major shift, changing production teams and deciding to focus on the North American market, which, despite countless successes in Great Britain and Europe, had still eluded them. This change paid off with the hit "Fox On The Run", which reached number 2 in Great Britain and a surprising number 5 in the United States. After a long tour of America, they decided to relocate there and record their most musically ambitious album, "Off The Record". Fueled by their worldwide popularity, the band embarked on numerous tours of Europe, Japan, and even the Far East, achieving unprecedented box office success in the London band's career. Amidst this whirlwind of success, in 1978 they released their sixth album, "Level Headed", where they demonstrated their complete departure from the aggressive sounds of their glam and heavy rock, definitively embracing a melodic and eclectic rock style. Tracks like "Love Is Like Oxygen", with its distinctly pomp rock feel, which conquered charts worldwide, contrasted with others closer to the Californian sound, such as "Silverbird" and "California Nights", the funk rock of "Strong Love", the addictive ballads of "Dream On", and forays into avant-garde rock with the surprising "Air On A Tape Loop". Despite this stylistic diversity, the album received a modest reception on the charts, which precipitated the departure of their vocalist, Brian Connolly, thus ending Sweet's golden era and becoming one of the most cherished memories in rock music.
