The successful progressive metal band Dream Theater released their debut studio album When Dream and Day Unite in 1989. With Charlie Dominici on vocals they took their first step in becoming one of the worlds best known bands in the progressive metal. It’s their shortest release, but one in which you can hear what later became the signature of the band. With shreddy riffs and jazzy signatures the band putted their influences out of 70s and 80s progrock. As a milestone in the evolution of progressive metal it’s an album full of atmospheric keyboard sounds, epic vocals and some powerful riffs. Charlie Dominici got some similarity with the voice of Geddy Lee and even the melodies got some of the stronger parts from Rush. But all to all it’s just a great start in the massive popularity they would receive a few years later. Dream Theater is one of the most successful bands in the progressive metal. After releasing their first top selling album Images and Words (1992) they were performing to bigger audiences. To date has they sold over 13 million records worldwide.
