BlackJack is a Swedish dansband that made its album debut in 1991 and eventually ascended to Top Ten success in 2008 with the greatest-hits collection Inget Stoppar Oss Nu "Inatt Inatt": Det Bästa med Black Jack.
Founded in 1990 in Sundsvall, Sweden, the band is comprised of Tony Ljungström (vocals, guitar), Ove Olsson (guitar), Morgan Östlin (saxophone), Peder Matz (keyboards), and Mikael Östlin (drums). BlackJack made their full-length album debut in 1991 with Den Stora Kärleken, followed by Om Det Känns Rätt in 1996 and Du Och Jag Och Kärleken in 1998. After the turn of the century, the band released the albums En Gång Till (2001), Fina Flickor (2004), and Vad Vore Livet Utan Kvinnor (2006) and began hitting the lower reaches of the Swedish albums chart. The double-disc greatest-hits collection Inget Stoppar Oss Nu "Inatt Inatt": Det Bästa Med Black Jack (2008), released on the label Frituna in association with EMI, was far and away the band's most successful release to date, reaching the Top Ten. The follow-up effort Summertime Blues (2009) was similarly popular, reaching number 11 on the albums chart and spawning the single "Mona Lisa." ~ Jason Birchmeier, Rovi
