In 1977 Warner Bros. created a record label Pacific to release music by their successful songwriters who were also performers. The first artist signed was Alan O'Day, writer of the Righteous Brothers' "Rock and Roll Heaven" and Helen Reddy's "Angie Baby." His first single was "Undercover Angel" and it turned into a #1 pop smash. Follow ups failed to reach the pop top 40 and Alan O'Day became a legendary one hit wonder. He died this past Saturday following a battle with cancer. Although he never again enjoyed the commercial success of "Undercover Angel," Alan O'Day continued to participate in the music industry until his death. He received an Emmy Award nomination for music written for the Muppet Babies animated TV series in the 1980s. Listen to "Undercover Angel" below.

This past weekend Stone Temple Pilots performed live in Los Angeles at KROQ's annual Weenie Roast. The performance featured their new lead vocalist Chester Bennington of Linkin Park. He replaces the band's long time leader Scott Weiland who was officially ousted by other group members earlier this year. Chester Bennington will not leave Linkin Park, but he has already recorded new music with Stone Temple Pilots. The song "Out Of Time" was performed at the Weenie Roast, and it is now available for free download.

Stone Temple Pilots blasted to prominence with the release of their debut album Core in 1992. It included the top 40 pop hit single "Plush" and has been certified eight times platinum. Two more multi-platinum albums followed as well as four more top 40 pop hits including the top 20 smash "Interstate Love Song." Struggles with drug addiction for lead vocalist Scott Weiland led to many ups and downs for Stone Temple Pilots through the years. The group's most recent album, a self-titled set, was released in 2010 and hit #2 on the album chart while producing their first alternative rock #1 hit "Between the Lines." Listen to Stone Temple Pilots led by Chester Bennington below.

One of the definitive sounds of American rock music in the 1960s was the keyboard playing of Ray Manzarek in classic songs by the Doors. Today he passed away at age 74 in Germany where he was battling bile duct cancer. The story of the Doors began in 1965 with a chance meeting between vocalist Jim Morrison and Ray Manzarek. The group released their self-titled debut album in 1967. The first single "Break On Through (To the Other Side)" failed to gain strong radio attention, but its follow up "Light My Fire" was a #1 smash. It was the first of three top 10 pop hit singles for the band. The Doors were inducted into the Rock and Roll Hall of Fame in 1993. The group broke up in 1973 two years after the death of lead singer Jim Morrison. The remaining group members reunited at various points in the past 20 years. Check out Ray Manzarek performing with the Doors below.

This past weekend Denmark continued the recent success of Scandinavian nations at the annual Eurovision Song Contest. Countries from that region have now won in three of the last five years. This year Denmark took home the top prize with a folkish flute-fueled ballad "Only Teardrops" performed by Emmelie De Forest. She is only 20 and recently released her debut album, also titled Only Teardrops, through Universal. Denmark's last victory at Eurovision was in 2000.

The UK's high profile Bonnie Tyler continued the nation's unfortunate performance in recent years by finishing 19th out of 26. She did end in a better position than Engelbert Humperdinck last year who finished second to last. Azerbaijan came in second at the competition but was far behind Denmark. Ukraine came in third. The Eurovision Song Contest has been taking place every year since 1956. It is one of the largest annual music competitions in the world. By winning this year's competition, Denmark won the right to host next year's event.
