The act is the third in the 2010s to lead with its first two charting singles.

Greta Van Fleet sends its second straight single to No. 1 on Billboard's Mainstream Rock Songs airplay chart, as "Safari Song" rise 2-1 on the ranking dated Feb. 24.

"Safari" marks the Michigan rockers' second No. 1 of two charted singles, as "Highway Tune" ruled the Mainstream Rock Songs chart for five weeks, beginning on the list dated Sept. 16, 2017.

Greta Van Fleet becomes the latest act to top the tally with its first two entries, with just two other acts having done so in the 2010s: Red Sun Rising (with "The Otherside" on Oct. 31, 2015, and "Emotionless" on May 7, 2016) and The Pretty Reckless ("Heaven Knows," March 22, 2014, and "Messed Up World," Sept. 13, 2014; the group's subsequent two entries also reached No. 1, with its four leaders in its first four tries a feat unmatched by any other act in the chart's 37-year history).

The ascent of "Safari," which concurrently climbs 17-15 on the all-rock-format Rock Airplay chart (4.7 million audience impressions in the week ending Feb. 15, according to Nielsen Music), is the latest triumph for Greta Van Fleet. In addition to its No. 1s on Mainstream Rock Songs, the band's first two releases – 2017's Black Smoke Rising EP and From the Fires double-EP – have made inroads on Billboard's rock album charts, with the latter having debuted at No. 1 on the Dec. 2, 2017-dated Hard Rock Albums ranking with 15,000 equivalent album units.

To date, Black Smoke Rising has moved 70,000 units (including 47,000 in traditional album sales) in the U.S., while From the Fires has earned 104,000 units (74,000 in album sales). Both sets feature "Safari."

The four-piece is currently at work on its debut full-length, with an anticipated release date sometime in mid-2018.
