Background: Frenzal Rhomb is an Australian punk rock band that formed in 1992, with Jason Whalley on lead vocals and rhythm guitar during this entire period. In 1996, Lindsay McDougall joined the line-up on lead guitar and backing vocals. Three of the group's albums have entered the top 20 on the ARIA Albums Chart: A Man's Not a Camel (1999),
Context: In July 1996, Frenzal Rhomb released their second album, Not So Tough Now, which was produced by Tony Cohen (Nick Cave and the Bad Seeds, TISM, Dave Graney), Kalju Tonuma (Nick Barker, The Mavis's) and Frenzal Rhomb. Just after its appearance, Costello was replaced by Lindsay McDougall on lead guitar and backing vocals - Costello left to attend university and become an animal rights activist. In November, the group issued a CD EP, Punch in the Face and, in January 1997, performed at Big Day Out. Late that year they toured the US supporting Blink-182.  In September 1997, their third LP, Meet the Family, was released, which reached the top 40 on the ARIA Albums Chart and became their first certified gold album by ARIA. It spawned three singles, "Mr Charisma" (June), "There's Your Dad" (September), and "Mum Changed the Locks" (April 1998). The latter title refers to McDougall telling his mother he was going out to a movie when leaving for an interstate tour and returning to find his key no longer opened the front door. Also in April, Gordon "Gordy" Forman replaced Nykyruj on drums, and they toured Australia with US ska band Blue Meanies. Frenzal Rhomb were the head-liners for the Australian leg of the 1998 Vans Warped Tour and they were recruited for the US edition. A 1998 version of Meet the Family contained a bonus disc, Mongrel, that was recorded live on this US leg.  In March 1999, they released their next album, A Man's Not a Camel, which was produced by Eddie Ashworth and was supported by a nationwide tour. As from November 2011, it remains Frenzal Rhomb's highest charting album, reaching No. 11. It spawned their highest charting single, "You Are Not My Friend" (August), which reached No. 49. Allmusic's album reviewer Mike DaRonco felt "the first two songs are great in that catchy, playful pop-punk sort of way, but the rest ... fall under the trap of having all their tracks sounding like one big, long song". The album also features fan favourites "We're Going Out Tonight" and "Never Had So Much Fun".  According to the band's website, US gigs were dropped after Whalley suffered a heart attack in late 1999 and the group spent the first few months of 2000 inactive. Whalley later denied that he had had a heart attack with "a lot of things on our Web site are greatly exaggerated. There was also a thing about my having trench rot, the World War I disease, but that's not true either".
