Lata considered Asha's act of eloping with her lover as irresponsible, leaving her alone to sing and earn for the family. This led to tensions between them. Asha herself accepted in an interview — "It was a love marriage and Lata didi did not speak to me for a long time. She disapproved of the alliance." At one time, their relationship was very adversarial and there have been periods of non-communication.
In her initial days in the industry, Asha always played second fiddle to her elder sister. Some say that Lata had once criticised Asha's relationship with O. P. Nayyar. This widened the rift between the two sisters and O P Nayyar also decided that he would never work with Lata. O.P. Nayyar had once revealed "Asha and Lata, staying in opposite flats at Bombay 's Peddar Road , had a common maidservant. Now this maidservant had merely to come and tell the younger sister that Lata had just recorded something wonderful for Asha to lose her vocal poise. Such was her Lata phobia that it took me some months to convince Asha that she had a voice individualistic enough to evolve a singing style all of her own." Asha once said that she has worked for years to create a voice and a style that was different from Lata, so that she could carve her own niche and not be banished to live in her sister's shadow.
Asha and Lata have also sung together. Their first duet was for the film
The movie Saaz, was supposedly based on Lata and Asha's rivalry. Asha said about the movie — "To have two women in long plaits, take a couple of incidents and exaggerate them into a 3-hour film is such a waste of time." In the last few years, Asha and Lata have often been seen in public, enjoying each other's company. In an interview with The Times of India, Asha once said - "I remember, sometimes both of us would be at a function and some industry types would ignore me and interact only with her, as if to prove their loyalty. Later, didi and I would have a good laugh!"
Private albums-
In a rare feat, noted lyricist Gulzar, music director R.D. Burman and Asha Bhosle, came together in 1987, to create a double album, titled, Dil Padosi Hai, which was released on September 8, 1987. In 1995, Asha underwent the gatha bandan (thread-tying) ceremony withHindustani classical music maestro Ali Akbar Khan to learn a classical repertoire held within the Maihar gharana (stylistic school of Indian classical music), as handed down to Khan by his father Allauddin Khan (the guru of Ravi Shankar). Later, Asha and Ustad Ali Akbar Khan recorded eleven fixed compositions (or bandishes) in California for Legacy, a private album that earned them a Grammy Award nomination.
In 1990s, Asha experimented with remixed R.D. Burman songs. She was criticized by many, including Khayyam for tampering with old melodies. Nevertheless, albums like Rahul And I became quite popular. In 1997, Asha did a private Indipop album Janam Samjha Karo withLeslie Lewis. The album was hugely popular and won her many awards including the 1997 MTV Award.
Asha had been once asked by director B R Ishaara to compose music for one of his films, but she had politely declined. In 2002, she turned music composer with the album Aap Ki Asha, an eight-song music and video album. The lyrics were written by Majrooh Sultanpuri (his last lyrics). The album was released by Sachin Tendulkar on May 21, 2001 at a lavish party in Mumbai. The album received mixed reviews.
Asha had spotted Pakistani singer Adnan Sami's talent when he was about 10 years old. At that time, she was performing in London , with R D Burman. It was she who had asked him to pursue his interests in music seriously. When Adnan grew up and became a professional musician, Asha sang the title duet with him for his best-selling album Kabhi to nazar milao. The two came together again in the album Barse Badal. The album comprises eight songs, based on Indian Classical music. She contributed the song Yun Na Thi to the recording Womad Talking Book Volume Four: An Introduction to Asia 1 on Womad Records.
Asha has sung ghazals for many albums like Meraj-E-Ghazal, Aabshar-E-Ghazal and Kashish. In 2005, Asha released a self-titled album as a tribute to the four ghazal maestros - Mehdi Hassan, Ghulam Ali, Farida Khanum and Jagjit Singh. The album features eight of her favorite ghazals like Farida Khanum’s Aaj Jaane Ki Zid Na Karo, Ghulam Ali’s Chupke Chupke, Aawargi and Dil Mein Ek Lahar, Jagjit Singh’s Ahista Ahista and Mehdi Hassan’s Ranjish Hi Sahi, Rafta Rafta and Mujhe Tum Nazar Se. These classic ghazals were recreated with modern sounds by musician Pandit Somesh Mathur. The album was aimed at the younger generation, who, according to Asha, are "turned off" by the traditional sounds of tabla and sarangi.
Numerous compilations of Asha's songs have been released as well. To commemorate her 60th birthday, EMI India released three cassettes:Bala Main Bairagan Hoongi (devotional songs), The Golden Collection: Memorable Ghazals (non-film ghazals by composers such as Ghulam Ali, R.D. Burman and Nazar Hussain), and The Golden Collection: The Ever Versatile Asha Bhosle (44 popular film songs).
