Sarada Devi (Bengali: সারদা দেবী;  Sharodā Debi (help·info)) (22 December 1853 – 20 July 1920), born Saradamani Mukhopadhyaya (Bengali: সারদামণি মুখোপাধ্যায়), was the wife and spiritual counterpart of Ramakrishna Paramahamsa, a nineteenth century mystic of Bengal. Sarada Devi is also reverentially addressed as the Holy Mother (Sri Maa or শ্রীমা) by the followers of the Ramakrishna monastic order. Sarada Devi played an important role in the growth of the Ramakrishna Movement.

Sarada Devi was born in Jayrambati. At the age of five she was betrothed to Ramakrishna, whom she joined at Dakshineswar when she was in her late teens. According to her traditional biographers, both lived lives of unbroken continence, showing the ideals of a householder and of the monastic ways of life. After Ramakrishna's death, Sarada Devi stayed most of the time either at Jayrambati or at the Udbodhan office, Calcutta. The disciples of Ramakrishna regarded her as their own mother, and after their guru's death looked to her for advice and encouragement. The followers of the Ramakrishna movement regard Sarada Devi as an incarnation of the Divine Mother.

Eric Patrick Clapton, CBE, (born 30 March 1945) is an English guitarist and singer-songwriter. Clapton is the only three-time inductee to the Rock and Roll Hall of Fame: once as a solo artist, and separately as a member of The Yardbirds and Cream. Clapton has been referred to as one of the most important and influential guitarists of all time. Clapton ranked second in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time" and fourth in Gibson's Top 50 Guitarists of All Time.

In the mid 1960s, Clapton departed from the Yardbirds to play blues with John Mayall & the Bluesbreakers. In his one-year stay with Mayall, Clapton gained the nickname "Slowhand". Immediately after leaving Mayall, Clapton formed Cream, a power trio with drummer Ginger Baker and bassist Jack Bruce in which Clapton played sustained blues improvisations and "arty, blues-based psychedelic pop." For most of the 1970s, Clapton's output bore the influence of the mellow style of J.J. Cale and the reggae of Bob Marley. His version of Marley's "I Shot the Sheriff" helped reggae reach a mass market. Two of his most popular recordings were "Layla", recorded by Derek and the Dominos, another band he formed and Robert Johnson's "Crossroads", recorded by Cream. A recipient of seventeen Grammy Awards, in 2004 Clapton was awarded a CBE for services to music. In 1998, Clapton, a recovering alcoholic and drug addict, founded the Crossroads Centre on Antigua, a medical facility for recovering substance abusers.

Luciano Pavarotti, Cavaliere di Gran Croce OMRI (12 October 1935 – 6 September 2007) was an Italian operatic tenor, who also crossed over into popular music, eventually becoming one of the most commercially successful tenors of all time. He made numerous recordings of complete operas and individual arias, and established himself as one of the finest tenors of the 20th century. He was one of The Three Tenors and became well known for his televised concerts and media appearances. Pavarotti was also noted for his charity work on behalf of refugees and the Red Cross, amongst others.

Pavarotti began his professional career as a tenor in 1961 in Italy. That same year, he made his first international appearance in La traviata in Belgrade, Yugoslavia. He sang in opera houses in addition to Italy, in the Netherlands, Vienna, London, Ankara, Budapest and Barcelona. The young tenor earned valuable experience and recognition while touring Australia at the invitation of soprano Joan Sutherland in 1965. He made his United States debut in Miami soon afterwards, also on Sutherland's recommendation. His position as a leading lyric tenor was consolidated in the years between 1966 and 1972, during which time he first appeared at Milan's La Scala and other major European houses. In 1968, he debuted at New York City's Metropolitan Opera as Rodolfo in Puccini's La bohème. At the Met in 1972, in the role of Tonio in Donizetti's La fille du régiment he earned the title "King of the high Cs" when he sang the aria "Ah mes amis ... pour mon âme". He gained worldwide fame for the brilliance and beauty of his tone, especially into the upper register. He was at his best in bel canto operas, pre-Aida Verdi roles and Puccini works such as La bohème, Tosca and Madama Butterfly. The late 1970s and 1980s saw Pavarotti continue to make significant appearances in the world's foremost opera houses.

Arvo Pärt (born 11 September 1935; Estonian pronunciation: [ˈɑrvo ˈpært]) is an Estonian classical composer and one of the most prominent living composers of sacred music. Since the late 1970s, Pärt has worked in a minimalist style that employs his self-invented compositional technique, tintinnabuli. His music also takes inspiration from Gregorian chant.

Pärt was born in Paide, Järva County, Estonia. A prolonged struggle with Soviet officials led him to emigrate with his wife and their two sons in 1980. He lived first in Vienna, where he took Austrian citizenship, and then re-located to Berlin. He returned to Estonia around the turn of the 21st century and now lives alternately in Berlin and in Tallinn.

Familiar works by Pärt are Cantus In Memoriam Benjamin Britten for string orchestra and bell (1977) and the string quintet "Fratres I" (1977, revised 1983), which he transcribed for string orchestra and percussion, the solo violin "Fratres II" and the cello ensemble "Fratres III" (both 1980).
