Acoustic music comprises music that solely or primarily uses instruments which produce sound through entirely acoustic means, as opposed to electric or electronic means. The retronym "acoustic music" appeared after the advent of electric instruments, such as the electric guitar, electric violin, electric organ and synthesizer.

Performers of acoustic music often increase the volume of their output using electronic amplifiers. However, these amplification devices remain separate from the amplified instrument and reproduce its natural sound accurately. Often a microphone is placed in front of an acoustic instrument which is then wired up to an amplifier.

Following the increasing popularity of the television show MTV Unplugged during the 1990s, acoustic (though in most cases still electrically amplified) performances by musical artists who do not usually rely on electronic instruments became colloquially referred to as "unplugged" performances.

Writing for Splendid, music reviewer Craig Conley suggests, "When music is labeled acoustic, unplugged, or unwired, the assumption seems to be that other types of music are cluttered by technology and overproduction and therefore aren't as pure."

Robert James "Bob" Ritchie (born January 17, 1971), known by his stage name Kid Rock, is an American singer-songwriter, musician, multi-instrumentalist and rapper with five Grammy Awards nominations. Kid Rock released several studio albums that mostly went unnoticed before his 1998 record Devil Without a Cause, released with Atlantic Records, sold 11 million albums behind the hits, "Bawitdaba", "Cowboy", and "Only God Knows Why". In 2000, he released The History of Rock, a compilation of remixed and remastered versions of songs from previous albums as well as the hit single, "American Bad Ass" and the previously unreleased "Abortion".

Kid Rock released the follow-up in 2001, Cocky. After a slow start, his country-flavored hit "Picture" with Sheryl Crow resurrected the album and it went gold as a single and pushed the album's sales over 5 million. It was followed by 2003's self-titled release, which went platinum in the USA and reached No. 8 on the Billboard charts. In 2006 he released Live Trucker, a greatest hits live album that went mostly unnoticed.

Avril Ramona Lavigne (pronunciation: /ˈævrɨl ləˈviːn/; AV-ril lə-VEEN; born 27 September 1984) is a Canadian singer-songwriter. She was born in Belleville, Ontario, but spent most of her youth in the small town of Napanee. By the age of 15, she had appeared on stage with Shania Twain; by 16, she had signed a two-album recording contract with Arista Records worth more than $2 million. In 2002, when she was 17 years old, Lavigne broke onto the music scene with her debut album Let Go.

Let Go made Lavigne the youngest female soloist to reach No. 1 in the UK, and the album was certified four-times platinum by the Recording Industry Association of America. By 2009, over 16 million copies had been sold worldwide. Her breakthrough single, "Complicated", peaked at No. 1 in many countries around the world, as did the album Let Go. Her second album, Under My Skin, was released in 2004 and was her first album to peak at No. 1 on the U.S. Billboard 200, eventually selling more than 10 million copies worldwide. The Best Damn Thing, Lavigne’s third album, was released in 2007, becoming her third No. 1 album in the UK Albums Chart and featuring her first U.S. Billboard Hot 100 No. 1 single, "Girlfriend". Lavigne has scored six number-one singles worldwide, including "Complicated", "Sk8er Boi", "I'm with You", "My Happy Ending", "Nobody's Home", and "Girlfriend". With more than 30 million copies of her albums sold worldwide, Lavigne is one of the top-selling artists releasing albums in the U.S., with over 10.25 million copies certified by the RIAA. Her fourth studio album, Goodbye Lullaby, was released in March 2011. Goodbye Lullaby gave Lavigne her fourth top 10 album on the U.S. Billboard 200 and the UK Albums Chart and her third No. 1 album in both Japan and Australia. Three months after the release of Goodbye Lullaby, Lavigne began work on her fifth album, which will be released on Epic Records following her departure from RCA Records.
