Peter learned to play guitar before he had finished high school, but spent a short time pursuing a comedic acting career. Once settled in Chicago, he began playing live in small bars in Chicago, the midwest, and even multiple tours to the UK. Besides Peter, there have been other members of "Nice Peter": Pauly Doerr on bass and vocals, Kristen Regester on drums and vocals, and Matt Donehoo on drums and vocals.
One of the most famed and diverse YouTube artists, NicePeter has now risen to the level of international fame. His channel - Epic Rap Battles Of History - created with his friend and partner, EpicLloyd, is one of the most watched on You Tube.
The series pits famous historical and pop culture figures, either fictional or otherwise, against one another (e.g.: Darth Vader vs. Adolf Hitler) in a rap battle format. Although early episodes of the series featured only Nice Peter and Epic Lloyd, later episodes have regularly featured guest appearances from other digital celebrities such as Lisa Donovan as Sarah Palin, Timothy DeLaGhetto as Kim Jong-il, Alex Farnham as Justin Bieber, MC Mr. Napkins as Albert Einstein, Colin J. Sweeney as Billy Mays, George Watsky as William Shakespeare, DeStorm Power as Mr. T, Prank Vs. Prank as Leonidas and Gorgo , Rhett and Link as The Wright Brothers, and Bentley Green as Young Michael Jackson. Epic Rap Battles of History are housed on its own YouTube channel since December 2011 according to Maker Studios which produces and distributes the series.
The 15th Epic Rap Battles of History, called the "Final Battle", was actually a season finale. Epic Rap Battles returned in December 8, 2011, hosted on their new channel, YouTube/ERB, with Behind the Scenes on their second channel, YouTube/ERB2.
Peter and Maker Studios have finished the website for Epic Rap Battles of History and people can now vote for who they think won the battle, plus bios for all the characters that were in the series.
The series has been one of the most viewed series in YouTube history and has vaulted Nice Peter's YouTube channel into 89th most viewed of all-time in YouTube history. As of early 2012, all the rap battles combined have over 416 million views.
As of April 2012, he is the 31st most subscribed of all time and the 7th most subscribed musician with over 1.5 million subscribers. The day after hitting one million subscribers, the video game and news channel G4 crowned Nice Peter the King of Dot Com Comedy on "Attack of the Show". His videos have received over 454 million views in his main channel plus 79 million views on his new channel ERB, and have been featured on the Huffington Post, Billboard.com, and the January 2012 issue of Wired Magazine. A recent interview with Forbes Magazine details Peter and his Epic Rap Battle of History partner Lloyd Ahlquist's rise to YouTube fame.
