The rockers' fourth self-titled release -- their first color-monikered album since 2008 -- opens with 45,000 copies sold. Plus, BABYMETAL sets a new bar for Japanese rock acts.

Blue, green, red and now white -- whatever the color, chances are it's going to spell success for Weezer.

And, indeed, it does again, as the California rockers' 10th album, Weezer, its fourth self-titled record, widely referred to as the White Album, debuts at No. 1 on Billboard's Top Rock Albums and Alternative Albums charts (dated April 23) with 45,000 copies sold in its first week, according to Nielsen Music.

The Rivers Cuomo-led quartet's first album since 2014's Everything Will Be Alright in the End marks the band's second chart-topper on either ranking, following 2009's Raditude. (The Top Rock Albums and Alternative Albums charts began in 2006 and 2007, respectively.) The band scores its best sales week since 2010's Hurley, which also arrived with 45,000 (although slightly more than the new set's total before rounding off), and easily improves on previous album Everything, which sold 34,000 its first week.

On the Billboard 200, Weezer opens at No. 4, the band's highest peak since its last self-titled affair, aka the Red Album, also hit No. 4 in 2008. Weezer's personal best remains Make Believe, which opened at No. 2 in 2005.

After the lead single from the new set, "Thank God for Girls," hit No. 11 on Alternative Songs in February, follow-up "King of the World" debuts this week at No. 39, becoming Weezer's 25th title on the ranking. The band ranks in ninth place for the most entries in the chart's history, which dates to 1988; U2 leads with 41.

Below Weezer's new set, six other titles enter the Top Rock Albums top 10, led by Explosions in the Sky's The Wilderness at No. 2 (16,000 sold). The Texas post-rock act's LP also starts at No. 2 on Alternative Albums, marking its best rank on either chart. The Used follows at No. 3 on Top Rock Albums with the all-acoustic Live & Acoustic at the Palace, with 14,000 in first-week sales.

No. 4 on Top Rock Albums belongs to newly inducted Rock and Roll Hall of Famers Cheap Trick, as Bang Zoom Crazy…Hello starts with 14,000. It becomes the band's highest-charting album on Top Rock Albums, as well as its first top 40 title on the Billboard 200 since 1988's Lap of Luxury (No. 16, powered by its Billboard Hot 100 No. 1 power ballad "The Flame"). New single "When I Wake Up Tomorrow" is the group's first Mainstream Rock Songs entry since 1997, this week climbing 30-29.

Nos. 5 and 6 on Top Rock Albums belong to hard rock acts. Black Stone Cherry starts at No. 5 on the tally, and No. 1 on Hard Rock Albums, with 12,000 sold for Kentucky. The set is the Kentucky (naturally) rockers' second No. 1 on the latter list, following 2014's Magic Mountain. Meanwhile, Japanese metal idol act BABYMETAL begins at Nos. 6 and 2 on the charts, respectively, with Metal Resistance (12,000). BABYMETAL achieves the best rank on either chart for a Japanese act; previously, Dir En Grey reached No. 9 on Hard Rock Albums with 2011's Dum Spiro Spero, while no Japanese act had made the top 10 of Top Rock Albums.

Rounding out top 10 debuts on Top Rock Albums, Andrew Bird's Are You Serious opens at No. 7 with 11,000 sold. It's also Bird's first to chart on Alternative Albums, beginning at No. 5, and his second No. 1 on Folk Albums, following 2012's Break It Yourself.
