This double album is a compilation album of the Polish band Millenium, which contains the best tracks of all the albums Millennium has released back in the day. The band started in the year 1999 and released more than 12 albums over the years. Both discs are more than one hour long and most tracks are also longer than 5 minutes. The artwork of the album sleeve is very nicely done. It contains the album covers of their previous albums, circling around an ancient clock. The booklet shows which tracks are from which album. I find this a nice limited edition package!
