The band's early releases were metal with symphonic influences using the Roland synthesizer guitar and Moog Taurus pedals.
Knights of Heaven showed a move toward a more melodic rock based sound. Both were with the band through
Setting Fire to the Earth (1987), together with
Bloodgood and concluded the year playing the Ennepetal
Christmas Rock Night festival in Germany for the second time. In 1989 they did touring again in Australia and completed two tours in the
USSR. The same year they recorded
Knights of Heaven in
Los Angeles, produced by
John Elefante. Before breaking up in the latter part on 1990 they again toured in the United States and Canada. The band (Jet Circus) did make an American appearance at the "Cornerstone" festival in Bushnell, Ill., the weekend of July 4, 1991. The band re-formed in March 2003 to play at the final
Bobfest. The show was recorded by
Sveriges Radio and released to CD. The final Leviticus show was held in Hjo Sweden June 2003 a festival gig together with Swedish metal giants
In Flames. In 2011, Leviticus celebrated their 30 years anniversary with a concert, on May 7, 2011, at Valhall in Skövde, Sweden. The line-up was the same as on
Bobfest, 2003, with only one exception: Håkan Andersson replaced Niklas Franklin on the bass guitar, and also performed vocals. They have continued to play since. ==Side projects==
