Plus, Snoh Aalegra and Doja Cat debut.

Australian psychedelic rock group King Gizzard & The Lizard Wizard re-enters Billboard's Emerging Artists chart (dated Aug. 31) at No. 1, becoming the top emerging act in the U.S. for the first time, thanks to its new LP, Infest the Rats' Nest.

The set launches at No. 64 on the Billboard 200 with 10,000 equivalent album units, according to Nielsen Music, marking the group's third and highest-charting entry. Its Flying Microtonal Banana and Murder of the Universe reached Nos. 170 and 106 in March and July 2017, respectively.

Infest concurrently starts at No. 5 on Alternative Albums and No. 8 on Top Rock Albums, marking the act's first top 10 on each tally.

Although the seven-member group has a large catalog of music (Infest is the group's 15th studio album), it is eligible to appear on Emerging Artists since it hasn't yet cracked the top 25 of the Billboard 200 or notched multiple top 10 entries on Top Rock Albums. The band formed in 2010 and has developed a following on the strength of energetic live shows and its recorded output (having even released five studio albums alone in 2017).

The Emerging Artists chart ranks the most popular developing artists of the week, using the same formula as the all-encompassing Billboard Artist 100, which measures artist activity across multiple Billboard charts, including the Billboard Hot 100, Billboard 200 and the Social 50. (The Artist 100 lists the most popular acts, overall, each week.) However, the Emerging Artists chart excludes acts that have notched a top 25 entry on either the Hot 100 or Billboard 200, as well as artists that have achieved two or more top 10s on Billboard's "Hot" song genre charts and/or consumption-based "Top" album genre rankings.

Rounding out the Emerging Artists chart's top five, Saweetie dips to No. 2 after two weeks at No. 1, Shaed holds at No. 3, NLE Choppa keeps at No. 4 and X1 drops 2-5.

Among other Emerging Artists moves, Swedish pop/R&B singer Snoh Aalegra debuts at No. 19, as her sophomore LP, Ugh, Those Feels Again, bows at No. 9 on Top R&B Albums and No. 73 on the Billboard 200 (9,000 units).

Plus, 23-year-old rapper Doja Cat makes her Billboard chart debut, opening at No. 37 on Emerging Artists, as her debut studio album Amala launches at No. 162 on the Billboard 200 (6,000 units). She also earns her first career entry on the Hot 100, as "Juicy," with Tyga, opens at No. 83.
