Having a progressive/symphonic rock musical background, among other influences namely bands such as Genesis, Yes, Camel, Pink Floyd and Pendragon (and others), "Atrium" are born in late 2003. In 'Linha de Cascais' (Lisboa), the band 'Atrium' has it's birth in the two long term friends (Rui and Carlos) companionship who found each other after many years apart. After having several former members passing through, the band consolidates it's base line-up with the arrival of Pedro (2004) and Sérgio (2009). From the persistence of these years, 'Let Me Dream' studio work along with other newer compositions was the band 'business card' in live performances, such as Barclay James Harvest sold out concert in Aula Magna, Lisbon, where Atrium played as Special Guests. Atrium's latest studio album, '2011' is an ambitious symphonic/progressive rock comeback. Definitely, Atrium are intending to conquer a place in the Progressive Rock global panorama.
