Michael John Angelakos (born May 19, 1987) is an American musician, singer, songwriter, and record producer. He is best known as the frontman of the indietronica band Passion Pit.

The first Passion Pit songs, which would later become the Chunk of Change EP, were written by Angelakos at Emerson College as a belated Valentine's Day gift to his then-girlfriend. At first, he wrote and performed all his material alone using a laptop. After one of his solo shows in the Boston area, Ian Hultquist, who was attending Berklee at the time, approached Angelakos and expressed interest in creating and playing music collaboratively. They formed a group that consisted of Angelakos, Hultquist, Ayad Al Adhamy, Thom Plasse (bass), and Adam Lavinsky (drums). The band spent a considerable amount of time trying to flesh out a collaborative format and structure that would work best for them. Jeff Apruzzese and Nate Donmoyer joined the band shortly after they signed to Frenchkiss in 2008, replacing Plasse and Lavinsky, respectively. In 2012, Adhamy was replaced by Xander Singh.

The band's debut EP, Chunk of Change, was released on September 16, 2008. The first four tracks were those that Angelakos had written as a gift for his girlfriend, which had already become popular throughout the Emerson College campus, where Angelakos was attending classes at the time, and had been passing out his own, self-produced copies.

The first and only single to be released from the EP, "Sleepyhead", received a good deal of exposure through its use in numerous media campaigns and advertisements, while the video for the song, directed by The Wilderness, was included on Pitchfork's Top 40 Music Videos of 2008 list. The song contains samples of "Óró Mo Bháidín" by Irish singer and harpist Mary O'Hara.

Other songs from the EP received some exposure as well. "Cuddle Fuddle" was featured in E4's second series of The Inbetweeners and "I've Got Your Number" was used in an advertisement for the cash card from O2, Money in the UK.

The band's first full-length studio album, Manners, was released on May 18, 2009, in the UK and May 19, 2009, in the United States and Canada. In celebration, the band played their record release party on the 18th in New York City on a Rocks Off boat cruise.

To obtain a specific background vocal accompaniment the band was looking for on Manners, Passion Pit enlisted the help of the PS22 chorus, who recorded vocals in-studio for three of the album's songs: "The Reeling", "Little Secrets", and "Let Your Love Grow Tall." "The Reeling" was the first single to be released from the album and found success on the Billboard Alternative Songs chart in the fall of 2009, where it peaked at number 34 in October and "Little Secrets" was the third single to be released and had success on the chart as well, topping out at number 39. "Let Your Love Grow Tall" was never released as a single but had some exposure being used in the sixteenth episode of the fourth season of the TV series Ugly Betty.

The album's second single, "To Kingdom Come", was used in the Rhapsody commercial for its iPhone application.
