First time I heard Aisles was on their dark concept album 4:45AM. With Hawaii, they deliver another 80 minute concept album, about a group of human colonies surviving after the earth is destroyed. Musically it's a very interesting mix of melodic symphonic rock, transferring the sound of the 70s and 80s to a 21st century sound. There is no lack of musicianship in this band, and Angel is one of the best vocalists I know. Highlights for me: jazz rock infused The Poet, and the wonderful, very melodic, symphonic rock pieces CH-7 and Pale Blue Dot. Progressive Rock lives in Chile.
