Bubblegum pop (also known as bubblegum rock, bubblegum music, or simply bubblegum) is a genre of pop music with an upbeat sound contrived and marketed to appeal to pre-teens and teenagers, produced in an assembly-line process, driven by producers, often using unknown singers. Bubblegum's classic period ran from 1967 to 1972. The second wave of bubblegum started two years later and ran until 1977 when disco took over and punk rock emerged (some critics have claimed bubblegum influenced punk).

The genre was predominantly a singles phenomenon rather than an album-oriented one, the presumption being that teenagers and pre-teens had less money to spend on records and were thus more likely to buy singles than albums. Also, because many acts were manufactured in the studio using session musicians, a large number of bubblegum songs were by one-hit wonders. Among the best-known acts of bubblegum's golden era are 1910 Fruitgum Company, The Ohio Express and The Archies, an animated group which had the most successful bubblegum song with "Sugar, Sugar", Billboard Magazine's No. 1 single for 1969. Singer Tommy Roe, arguably, had the most bubblegum hits of any artist during this period.

Katheryn Elizabeth Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter and actress. Perry grew up with gospel music, and during her first year of high school she pursued a music career as Katy Hudson, releasing her first studio album called Katy Hudson which failed to chart. She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.

She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".

Ronald Belford "Bon" Scott (9 July 1946 – 19 February 1980) was a Scottish-born Australian rock musician, best known for being the lead singer and lyricist of Australian hard rock band AC/DC from 1974 until his death in 1980. He was born in Forfar and brought up in Kirriemuir, Scotland, before moving to Melbourne, Australia with his family in 1952 at the age of six. The family lived in the suburb of Sunshine for 4 years before moving to Fremantle, Western Australia.

Scott formed his first band, The Spektors, in 1964 and became the band's drummer and occasional lead vocalist. He performed in several other bands including The Valentines and Fraternity before replacing Dave Evans as the lead singer of AC/DC in 1974.

In the July 2004 issue of Classic Rock, Scott was rated as number one in a list of the "100 Greatest Frontmen Of All Time" ahead of Freddie Mercury and Robert Plant.Hit Parader ranked Scott as fifth on their 2006 list of the 100 Greatest Heavy Metal Vocalists of all time.

AC/DC's popularity grew throughout the 1970s, initially in Australia, and then internationally. Their 1979 album Highway to Hell reached the top twenty in the United States, and the band seemed on the verge of a commercial breakthrough. However, on 19 February 1980, Scott died after a night out in London. AC/DC briefly considered disbanding, but the group quickly recruited vocalist Brian Johnson of the British glam rock band Geordie. AC/DC's subsequent album, Back in Black, was released only five months later, and was a tribute to Scott. It went on to become the third best-selling album in history.

Urie attended Palo Verde High School, where he met future ex-Panic bassist Brent Wilson in his guitar class. Wilson asked Urie to try out for a band he was in, since they needed a replacement guitarist.

In a 2011 interview, Urie described himself as a "spazz in high school". He commented: "There was a kid that used to pick on me…he used to drop my food, and beat me up in little corners," he said. "Nothing serious, but tease me. I remember knocking his food out of his hand one time when he [was] in the middle of explaining something to his friends, and they all laughed, so I thought that was pretty nice. ‘Well, there you go buddy.’ I was able to get instant karma."
