By October of 2000, Sako had gathered together a new body of work,his fifth album, Gravity. Sako formally released the CD to a crowd of over 800 eager fans at Tower Records on November 19, 2000, in Glendale, California. Following the release, the album was on listening stands for over 2 months in both Tower Records and Virgin Records. It was also one of Tower Records best selling albums for 2 consecutive weeks.
The outstanding success of the Gravity album was marked by the hit song, Ganidzem. Through music promoter Stepan Partamian, Sako was introduced to duduk player Roubik Haroutounian. Upon hearing Ganidzem, Haroutounian improvised a duduk riff to go with the song. Sako was captivated by the accomplished playing of Haroutounian and instantly requested the dudukist have the piece recorded.
There was an overwhelming response from dedicated fans everywhere through e-mails, phone calls and letters, praising the album, and at the Third Annual AMAs, the album received 3 nominations including: Best Dance Album, Peoples Choice, and Best Album Cover. The Gravity album became Sako's boldest album yet.
Complimenting the song was an extraordinary video directed by Koji Zadori. The video was filmed in Death Valley, California, with a crew of over 30 people and became a smash hit. It was practically unheard of for an Armenian artist to create such a professional and exhilarating music video. For the first time in the Armenian market, people were paying money to play Sako's videos on television. Through Sako's creativity, a trend was created among the Armenian market, and more singers began shooting music videos, attempting to add originality.
On June 23, 2001, Sako set another milestone with his outstanding concert at the Alex Theater in Glendale, California.
