This collection represents more than 20 years work on the part of Neil Tennant and Chris Lowe. For the first several years of that career, they were famous world-wide, and quite a staple in the dance clubs and video programming in America and elsewhere. The first singles collection 'Discography' represented the beginning of the decline of 80s style dance music in America, but the music descended from this type remained strongly popular throughout the rest of the world, as the sold-out concert tours of the Pet Shop Boys everywhere except North America attests to. Many of the songs on this 'Pop-Art' collection will therefore be new to audiences whose interest in the Pet Shop Boys ended the hits from the 'Behaviour' era. This wonderful double CD - containing 35 tracks, including two songs previously unreleased in the U.S., "Miracles" and "Flamboyant" - spans all three labels they've recorded for domestically: EMI, Atlantic, and Sanctuary. Also, I like when they throw in surprises like slightly different versions of songs from their original album versions. If you already have the original albums, then it's nice to get the additional remixes. This sums up their career quite well. One often wonders why certain songs become singles, and others don't. Regardless, this is a great collection that you are sure to enjoy. A must-have for anyone who likes dance music, disco, electronic music, 80s music, the Pet Shop Boys, or who wants to have a complete music collection.
