The gal behind the #3 Hottest song of 2019 is levelling up for a big Australian tour.

Mallrat is stepping up to play theatre-sized shows this winter, taking in all ages dates in Adelaide, Sydney, and an under 18s show in her native Brisbane.

The increased rooms is to meet the ever-increasing popularity for 21-year-old songwriter and producer Grace Shaw, who snagged her second Hottest 100 Top 10 placing recently with 'Charlie' - the emotionally charged song she had to fight to get released as a single. Read more below.

How Mallrat's Hottest 100 hit 'Charlie' almost never happened "I kind of got that feeling as soon as I wrote it… I knew it was going to connect with other people.”

Following the success of her third EP Driving Music - sending her across Europe and the US to share stages with Maggie Rogers, Allday, and King Princess - Mallrat is currently "deep in the process" of writing and recording her debut album. (Eeeek!)

Tickets are on sale from Thursday 20 February, 1pm AEDT, but there's a fan presale kicking off Tues 18 Feb. View the dates below and more info at lilmallrat.com.
