When had that previously happened in the chart's nine-year history? Try never.
The onslaught of debuts breaks the former record of eight top 10 debuts in a week, achieved four times since the chart's Jan. 14, 2006, origin, most recently a year ago, on the Oct. 11, 2014, ranking (when alt-J led with This Is All Yours).
This week, Gilmour paces the field with 70,000 sold for Rattle That Lock, according to Nielsen Music. It's a triumphant week for the Pink Floyd guitarist, not only because of his No. 1 in a stacked field. It's also Gilmour's first No. 1 on the chart, both as a solo artist or as part of the iconic rock band. On the Nov. 29, 2014, chart, Pink Floyd's The Endless River, purportedly its final recording, debuted at No. 2, although with a significantly loftier 170,000 sold. Gilmour previously peaked as high as No. 3 on Top Rock Albums with 2006's On an Island (96,000 first-week sales). The new set also debuts at No. 5 on the all-genre Billboard 200, marking Gilmour's best rank peak as a solo act.
SHINING BRIGHT: Following Gilmour in the Top Rock Albums top 10 is a blitz of bows; only Five Finger Death Punch, whose Got Your Six debuted two weeks ago, is a holdover (No. 6, 19,000 sold).
Shinedown ranks as Gilmour's closest competitor, as the Florida quartet debuts at No. 2 with Threat to Survival (61,000), its fifth studio album. The record, led by single "Cut the Cord" (which led Mainstream Rock Songs airplay chart for seven weeks), brings the band's second-best peak on Top Rock Albums, trailing only 2012's No. 1 Amaryllis. The band also nabs its second-best sales week, topped only by Amaryllis' 105,000 first-week sum. The new LP additionally debuts at No. 1 on Hard Rock Albums, the band's second leader on the list (following Amaryllis).
SWIFT START: Gilmour and Shinedown's big debuts are followed by Ryan Adams' buzzy 1989 (No. 3), his full album cover of Taylor Swift's 2014 record of the same name. Adams' 1989 arrives with sales of 49,000 in its first week, his best single-week result since 2007's Easy Tiger (61,000). However, 1989 doesn't yield his greatest peak on the chart; last year's self-titled effort became his first No. 1.
As previously reported, Adams' lead 1989 single "Bad Blood" is finding favor at adult alternative radio.
ALSO ROLLING IN: Turns out Gilmour isn't the only famous classic rock guitarist getting in on the fun. Keith Richards' solo Crosseyed Heart starts at No. 4 on Top Rock Albums with 33,000 sold. It's the Rolling Stones guitarist's best sales week (since Nielsen began tracking sales in 1991) by a long shot; his previous best, 1992's Main Offender, peaked with 12,000 sold its seventh week on the Billboard 200.
Metalcore outfit blessthefall slots in at No. 8 on Top Rock Albums with 16,000 sold in the first week for its fifth album To Those Left Behind. Fellow metalcore act Atreyu clocks in at No. 9 with 15,000 copies sold of Long Live, while indie rockers the Front Bottoms manage a Top Rock Albums top 10 for the first time with Back on Top at No. 10, also earning a career-high sales week (11,000).
