Album

Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, then from 1948 as vinyl LP records played at 33 ¹⁄₃ rpm. Vinyl LPs are still issued, though in the 21st century albums sales have mostly focused on compact disc (CD) and MP3 formats. The audio cassette was a format used in the late 1970s through to the 1990s alongside vinyl.

An album may be recorded in a recording studio (fixed or mobile), in a concert venue, at home, in the field, or a mix of places. Recording may take a few hours to several years to complete, usually in several takes with different parts recorded separately, and then brought or "mixed" together. Recordings that are done in one take without overdubbing are termed "live", even when done in a studio. Studios are built to absorb sound, eliminating reverberation, so as to assist in mixing different takes; other locations, such as concert venues and some "live rooms", allow for reverberation, which creates a "live" sound. The majority of studio recordings contain an abundance of editing, sound effects, voice adjustments, etc. With modern recording technology, musicians can be recorded in separate rooms or at separate times while listening to the other parts using headphones; with each part recorded as a separate track.

Megadeth

Megadeth is an American thrash metal band from Los Angeles, California. The group was formed in 1983 by guitarist Dave Mustaine and bassist David Ellefson, shortly after Mustaine's dismissal from Metallica. A pioneer of the American thrash metal scene, the band is credited as one of the genre's "big four" with Anthrax, Metallica and Slayer, responsible for thrash metal's development and popularization. Megadeth plays in a technical style, featuring fast rhythm sections and complex arrangements; themes of death, war, politics and religion are prominent in the group's lyrics.

In 1985, the band released its debut album, Killing Is My Business... and Business Is Good!, on the independent label Combat Records. The album's moderate commercial success caught the attention of bigger labels, which led to Megadeth signing with Capitol Records. Their first major-label album, Peace Sells... but Who's Buying?, was released in 1986 and influenced the underground metal scene. Despite its prominence in thrash metal, frequent disputes between its members and substance abuse issues brought Megadeth negative publicity during this period.

Risk

Risk is the potential of gaining or losing something of value. Values (such as physical health, social status, emotional well-being or financial wealth) can be gained or lost when taking risk resulting from a given action or inaction, foreseen or unforeseen. Risk can also be defined as the intentional interaction with uncertainty. Uncertainty is a potential, unpredictable, and uncontrollable outcome; risk is a consequence of action taken in spite of uncertainty.

Risk perception is the subjective judgment people make about the severity and probability of a risk, and may vary person to person. Any human endeavor carries some risk, but some are much riskier than others.

Rust in Peace

Rust in Peace is the fourth studio album by American thrash metal band Megadeth. It was released on September 24, 1990 by Capitol Records and was produced by Mike Clink. Following the departure of Jeff Young and Chuck Behler in 1989, Rust in Peace is the first album to feature guitarist Marty Friedman and drummer Nick Menza. Rust in Peace received universal acclaim by fans and critics, and was responsible for bringing Megadeth to the attention of a mainstream metal audience. It has been cited as one of the best thrash metal records of all time by publications such as Decibel and Kerrang! and listed as one of the 1001 Albums You Must Hear Before You Die. The album was nominated for Best Metal Performance at the 33rd Grammy Awards.

Two singles were released from the album: "Hangar 18" and "Holy Wars... The Punishment Due", which have become staples of the band's live performances. Rust in Peace features complex musical structures and lyrical themes such as nuclear war and UFOs. The album's cover art references "Hangar 18". A remixed and remastered version featuring four bonus tracks was released in 2004. In 2010, the band announced a North American tour to commemorate the album's 20th anniversary. The performance at the Hollywood Palladium was filmed and released as Rust in Peace Live on CD, DVD and Blu-ray later that year.
