Millionaires have come a long way since their MySpace beginnings. In 2007 they were a trio featuring sisters Melissa and Allison Green and their friend Dani Artaud. They recorded the party pop single “I Like Money” with an early version of GarageBand on an old Apple desktop computer. Fast forward to 2013, and Artaud has left Millionaires to form the indie pop band Mr. Downstairs. Now a duo, the Green sisters open Millionaires' debut album, Tonight, with “Put It in the Air”—a humorous party anthem that blends industrialized electro textures with gratuitous amounts of Auto-Tune and bass. Over this, Melissa and Allison swap rhymes and sound like an aloof Kreayshawn. “Kitty Go Hello” follows, with throbbing beats and seductive rhymes overflowing with clever innuendo. In the catchy electro-pop anti-serenade “One in a Million,” the sisters explicitly lambaste young male players who've done them wrong. It’s one of the catchiest tunes on Tonight, and the kinetic mechanics matched with lovelorn lyrics make Millionaires sound like the little sisters of Nicki Minaj and Ke$ha. The raunchy “Boss B*tch” recalls Lil' Kim.
