Write a question about the following article: On April 15, 2012, a "hologram" of Shakur (technically a 2-D video projection) performed his songs "Hail Mary" and "2 of Amerikaz Most Wanted" with Snoop Dogg at the Coachella Music Festival. The effect was created using an optical illusion called Peppers ghost. The video footage was created by visual effects company Digital Domain. The Wall Street Journal reported Dr. Dre and Snoop Dogg were in talks of a possible tour involving the two rappers and the projection version of Shakur, which was later turned down by Dr. Dre. Tupacs 1998 Greatest Hits album returned to the Billboard 200 the following week for the first time since 2000, reaching No. 129 with 4,000 copies sold according to Nielsen SoundScan (a gain of 571% over the previous week). The MCs other albums also saw gains, including All Eyez On Me (2,000; up 95%) and Me Against the World (1,000; up 53%). His singles also saw a boost in sales. His biggest seller of the week was "Hail Mary"—the song his projection opened with at Coachella. His second biggest seller was his No. 1 Billboard Hot 100 hit "California Love" (featuring Dr. Dre and Roger Troutman), shifting 11,000 downloads (119% increase). His third best-seller was the second Tupac song that was performed at Coachella &ndash; "2 of Amerikaz Most Wanted" (with Snoop). It sold 9,000 (up 881%).
What Shakur single saw the greatest sales in the week after the "hologram" performance?
