Toto IV is the fourth studio album by American band Toto released in 1982 (see 1982 in music).

The album received six Grammy Awards including Record of the Year for "Rosanna", Album of the Year and Producer of the Year for the band. It reached number four on the Billboard Pop Albums chart shortly after its release in 1982. The single "Rosanna" reached number two on the Billboard Hot 100, while the album's third single, "Africa", became the group's only Hot 100 #1 hit. Both songs were smash hits in the UK as well, reaching no. 12 and no. 3 respectively. "I Won't Hold You Back" came next and reached the top 10 in the USA and the top 40 in the UK. With the success of "Africa", the album climbed back into the top 10 in early 1983.

The album featured a stronger dose of the pop/hard rock/R&B-fusion that had characterized their self-titled first album than had been heard on their previous two albums.^{[citation needed]}

Chaos Divine is a progressive metal band from Perth, Western Australia. The band consists of vocalist David Anderton, guitarists Simon Mitchell and Ryan Felton, bassist Michael Kruit and Drummer Ben Mazarol.
Chaos Divine's signature is very much what the name suggests - a blaze of thick riffage with a brick wall-sized sound that at times spirals into hypnotic melodies. Drawing influences from the heavy, progressive and melodic elements of bands such as Opeth, Dream Theater and Soilwork, this quintet forges a unique blend of brutal polyrhythmic metal and ambient contemporary rock.

Since 2005, the band has released two studio albums.

The 2006 Ratio EP, which saw the band tour nationally, was publicly voted as the second-best Australian metal release of its year on Triple J’s Full Metal Racket Program.

In late 2008, Chaos Divine completed their debut full-length debut album Avalon, recorded at Melbourne’s Sing-Sing Studios and released nationally through Firestarter Music. The album went on to win the West Australian Music Industry Awards (WAM) Industry's 2008 Song of the Year Award in the Heavy Rock/Metal category with the track 'Refuse the Sickness'. Chaos Divine was also among the top-five finalists nominated for the Metal/Hardcore award at the National MusicOz awards held in Sydney and broadcast live to a national television audience, in both 2007 and 2008. Avalon was also voted in the top 10 international metal albums of the year by Triple J.
