Venerable punk rockers Descendents bow at No. 2 on Billboard's Top Rock Albums and Alternative Albums charts (dated Aug. 20) with their seventh studio album, Hypercaffium Spazzinate, which opens with a career-best 15,000 sold, according to Nielsen Music.

The debut sum surpasses the 9,000 that the band's previous LP, 2004's Cool to Be You, sold in its debut week, marking a new best sales week for the act in the Nielsen era, which began in 1991.

Hypercaffium Spazzinate also marks Descendents' first album to chart on Top Rock Albums and Alternative Albums; the markers began in 2006 and 2007, respectively, and the four-piece had not released a record since then. The new set also enters at a career-high No. 20 on the Billboard 200, surging past 1996's Everything Sucks (No. 132).

Descendents first released an album, Milo Goes to College, in 1982, and the LP has since been acclaimed as influential in the punk genre.

Chris Robinson Talks Brotherhood, Black Crowes & More: 'I'll Let My Music & My Career Speak for Me'

The other top 10 debut on Top Rock Albums belongs to the Chris Robinson Brotherhood, led by Black Crowes frontman Chris Robinson. Anyway You Love We Know How You Feel, the blues rockers' fourth studio album, starts at No. 6 on Top Rock Albums and Alternative Albums with 6,000 copies sold, marking the group's highest peaks, besting 2014's Phosphorescent Harvest (Nos. 20 and 11 on the charts, respectively).

Robinson has previously enjoyed even greater success on Top Rock Albums, reaching the top 10 three times with the Black Crowes, including Warpaint's No. 3 peak in March 2008 (46,000 sold upon its debut). The Crowes arrived on the Billboard 200 in March 1990 with Shake Your Money Maker, which rose to No. 4 in April 1991. In May 1992, their The Southern Harmony and Musical Companion soared in at No. 1 (142,000 first-week copies sold).

The Top Rock Albums' No. 1 spot belongs to Twenty One Pilots' Blurryface, which rules for a seventh week with 16,000 copies sold (up 23 percent). The set debuted at No. 1 on the June 6, 2015, chart and has sold 1.034 million to date.
