Evans was born in the Welsh town of Carmarthen, and moved to Australia at the age of five with his parents. They settled in the Queensland city of Townsville, and later moved to Charters Towers, where he formed his first band at the age of seventeen. He later moved to Sydney.
Evans was one of several members of AC/DC before the band matured and began to play all original music, along with Colin Burgess and Larry Van Kriedt. He was a member of the band for less than ten months before officially being replaced by Bon Scott in October 1974. During his time with AC/DC, Evans recorded one single, a Young/Young composition ("Can I Sit Next To You, Girl"/ "Rocking in the Parlour") which was released in Australia and New Zealand. A low-budget promotional video for the demo was also shot. It peaked nationally at number 50 on the Aria (Kent) charts and then disappeared. The song was later re-recorded professionally with Bon Scott. Evans has cited jealousy as the reason for his dismissal, and has also said there would be no AC/DC if not for him.
After AC/DC, Evans joined Newcastle band Rabbit, replacing original singer Greg Douglas. Rabbit released 6 singles and two albums between 1975 and 1977. His other bands included Dave Evans & The Hot Cockerels and Thunder Down Under.
Evans has also released three solo albums. The first was a live recording, A Hell of a Night, which was a memorial gig for Bon Scott. It was recorded on the 20th anniversary of Scott's death, with Melbourne AC/DC tribute band Thunderstruck. The second, Sinner was released in February 2006. In April 2010 he released his Judgement Day album in the UK through independent label Rocksector Records.
In June 2012, Evans performed as guest vocalist for the Norwegian band Barbed Wire on a mini AC/DC tribute tour. The tour started with a concert on Trondheim Rock. Barbed Wire played as opening act to Twisted Sister. Evans then flew back to the UK for a 12-date headline tour, performing songs from Judgement Day and cover versions of classic AC/DC tracks written by the band after his departure.
In June/July 2013, Evans returned to the UK for a 14-date headline tour, celebrating 40 years of AC/DC. He released a single "Little Headbanger" from Judgement Day as a promo music video for the tour, but the music once again failed to make any charts. He also played four dates with Long Way to the Top – the AC/DC Spectacular.
Dave Evans returned to Europe In May 2014. He performed in Kiev in a show called "Ukraine still ROCKS!" and was supported by local AC/DC tribute band D/C Train. The show in Kiev was held in the Bike-Rock-N-Roll Club Route 66 on 24 May. Evans called it a historic event for him and rock music as a whole. In the same year the singer played in Brazil with his South American Badasses in São Paulo, Paranã and Santa Catarina.
On 22 January 2015, Evans performed in the US for the first time in a concert to coincide with The Rockin' Rag Magazine's annual NAMM Show, with San Diego AC/DC tribute band BACK 2 BLACK. They performed a second concert three days later at the Yost Theatre in Santa Ana, California. From there, he left the US for a European tour before returning to Australia. In October 2015, Evans performed four shows in Ohio and Pennsylvania with the Canton, Ohio-based AC/DC tribute band Thunderstruck.
