Phil Everly’s death has spurred thousands of fans to revisit the band’s music. After one-half of the Everly Brothers duo died Jan. 3 of chronic obstructive pulmonary disease, people have been snapping up the band’s albums and singles in both digital and physical versions.

The Everly Brothers’ catalog of albums saw a 455% increase in sales in the wake of the singer’s death, rising to 5,000 sold for the week, according to Nielsen SoundScan. But the biggest seller was the 25-song collection, “The Very Best of the Everly Brothers,” which sold 2,000 copies. It debuts at No. 8 on the Country Catalog Albums chart.

The act’s top-selling song of the week was “All I Have to Do Is Dream,” which moved 4,000 downloads, an increase of 490% from less than 1,000 a week ago. In total, 18,000 Everly Brothers songs were purchased this past week.

This story was first reported by Billboard.
