The world first met Maia when she was a 17-year-old singer with a ukulele and a now-famous screenname: mxmtoon. In 2017, and from the guest bedroom in her parents’ California home, the high-school student began posting covers of pop favorites and her own catchy confessional musings, tunes that spoke frankly of her setting’s assorted tribulations — dates and a lack thereof, online socializing and offline loneliness. A queer kid of mixed Chinese, German, and Scottish ancestry, Maia sang songs that expressed an interiority of the underrepresented with honesty, understanding, and hooks that could not be forgotten. mxmtoon became a streaming sensation, her teenage ditties defining a new era of what it meant to make bedroom pop. Stepping into the studio proper for her 2019 debut, the masquerade, mxmtoon became an avatar for the new bloom of representation and inclusion in American pop. When “prom dress” became a hit, Maia was still a teenager. In truth, only five years have passed since Maia’s self-made songs and videos began shaping a new sort of star through mxmtoon. But at least two of those years have, of course, passed like decades, each packed with enough worry and woe and loss and hope to catalyze aging at large. And so it goes with rising, mxmtoon’s bold and compelling and wise second album, a 12-song set that looks at the hardest lessons of these recent dark days and opts to surge forward through triumphs of pop-and-disco confessionalism.
