After completing the School for Journalism, Beeker started working as a reporter for the Limburg broadcaster L1. Although he felt at home in this work, he also began to explore his passion for music. This resulted in the founding of the band Ongenode Gaste. Since the late nineties, Beeker has made music under this name in changing lineups.[3]
Without Met Zònder embarrassment, he reached the final of the singer-songwriter competition of the Grote Prijs van Nederland.[3] In 2002 this song was included in the Amsterdamse Paradiso. In 2004 he received the ING-Pries veur ut Limburgs Leed.
In 2009 the song 'Mèt Of Zoonder Diech' was recorded, a collaboration between Peter Beeker and the Maastricht dialect band Rebzjie. The song appeared on the Rebzjie album 'Lankzaam Kump Later' and was released as a single in February 2010. The single entered at number one in the Limbo top 10 in March 2010 and also achieved a 15th place in the Limbo top 10 annual list, the Limbo top 50 2010.[4]
In 2010 he decided to start completely over. Beeker recruited drummer Jim Geurts and bassist Vincent van Haperen (both still active in Pitch Blond at the time). Later the band was supplemented with Jesper Driessen on guitar and Dick Franssen (Alquin) on the Hammond organ.
In the spring of 2011, a new record was recorded in two studio days. This record had nine tracks, including the single "Door Ut Stof Neet Mier"; a country rocker inspired by the track "Maggies Farm" by Bob Dylan. Filmmaker Rob Hodselmans (cameraman for Holland Sport, Sportpaleis de Jong, Pakhuis de Jong) made the video clip.
