[2][7] At the age of 13, she was accepted to the choir of Radio Denmark and was chosen to sing in an opera for children called Lykken og Forstanden.

After earning her high school diploma from Sankt Annæ Gymnasium in 1992, Lerche enrolled in a three-year Rytmikpædagog, a rhythm-based music education program.

[citation needed] After acting and singing in numerous musical theatre productions, including Sommer i Tyrol (The White Horse Inn) where she played the part of Annelise,[11] Anita released her first solo album, I Love a Piano in 2005.

It also features soft renditions of the American folk song "The House of the Rising Sun" and Eric Clapton's "Tears in Heaven."

She also recorded "Tid til Kærlighed (Time For Love)" as a part of the Danish charity telethon DM i indsamling 2005–Forældreløse børn i Afrika.

Lerche and her friends stayed at an apple orchard owned by Anurag Sood in Parvati Valley, district Kullu, Himachal Pradesh.

"It is very important to me to understand the literal meaning of each word and the full story of the songs I am singing.”[15] Lerche also received instruction from the late Rattan Singh Rajput, who was one of the driving forces behind her first Punjabi album.

Concerning the album, producer Satvinder Singh said, “With lot of hard work, today we got success.”[16] Throughout Heer from Denmark, Lerche pays tribute to the rich Punjabi culture.

The Times of India reported: “Anita has also rendered traditional ‘Heer’ in the album and succeeded in imbuing the depth, pain and passion of the rich composition.

[citation needed] For instance, Lerche created a Hindi song to celebrate the Indian Cricket team during the World Cup in both 2007 and 2011.

[4] The cricket songs were set to the tune of Lerche’s hit "Gori," with the words changed to support India's most popular team.

[26] The collaboration was arranged by Bhangra musician and producer King Gurcharan Mall, and the track was backed by his Indian drum group, Dhol Blasters.

Since Anita is a well-known name in Denmark, and she's done well for herself in Punjab, we wanted to see how far she could go.”[29] In 2011, Lerche was a featured artist on the recording of a musical drama, The Bollywood Trip.

[30] In 2012, producer Agiapal Singh Randhawa created a documentary about Lerche's life, achievements and love of Punjabi culture, called Kashish Punjab Di.

[6] Critics have reported that “Sadke Punjab Ton does highlight her appreciation and growing knowledge of Punjabi culture, but Anita lets her classical training shine in her new single ‘Merea Ranjha.’”[32] According to Lerche, "Merea Ranjha" was inspired by her personal life as well as her love of the classical folk tale on which the song "Heer" is based.

KP Singh, an artist and Sikh community leader in Indianapolis, expressed his excitement about the performance, writing: “I am familiar with Ms. Lerche's sensational talent and efforts to introduce Sikh sacred music and the robust Punjabi Bhangra music to the Western audiences.”[37][38] In 2014, Lerche became a member of the National Academy of Recording Arts and Sciences–Chicago Chapter, after moving to the United States as a permanent resident.

"I managed to obtain a Green Card as a unique artist in Punjabi culturally inspired music after two long years, but it was all worth it," she told one news outlet.

Indian Prime Minister Narendra Modi launched the collaboration video as a part of the 150-year birthday celebration of Mahatma Gandhi.

With her 2022 released single ‘Simran’, Lerche celebrates and recreates the time-honored Sikh devotional tradition of rhythmic chanting of sacred words during worship.

[citation needed] During the New York Fashion Week 2023 Lerche got to perform her original Punjabi songs on the Runway on Broadway in Gotham Hall,[52] representing the Randhawa Brands.

Her award-winning 2024 album, “Songs from the Kingdom of Denmark,” is a heartfelt homage to her Danish heritage, further enriching her diverse musical legacy.

Lerche has said, “I deeply feel that we all have an obligation to support the people in need.”[citation needed] She has performed benefit concerts[58] for Indianapolis-based Christel House International [5] in 2013, 2014, 2015,[59] 2016 and 2017.

[63] In 2016 Lerche was picked to be one of the artists featured on the album Music To Inspire against Human Trafficking initiated by Rukus Avenue and the UN, Blue Heart Campaign.

Even before her switch to Indian music, she participated in DM i indsamling 2005–Forældreløse børn i Afrika, a 24-hour Danish telethon that raised money for African orphans.

[12] The track "Tid til Kærlighed (Time For Love)," which features Lerche and four other prominent Danish vocalists, was recorded and released as a part of this program.

[citation needed] As well as Lerche's experience in musical theatre and the recording world, she has worked as a voice actor for Disney, Pixar and a Barbie books series.
