Apparently, talented Giacomo Puccini was so interested to convert it into an Italian opera and it took four years of Puccini repeatedly arguing with his publisher, and librettists until he was able to obtain its rights on 1895 with the help of Giuseppe Giacosa and Luigi Illica who converted its Italian libretto setting and have it officially performed as an opera.
"Tosca" is a compelling story incorporating a pinch of controversy, beautifully done through a collection of distinguishable set-pieces strung by equally memorable melodies which some find a mixture of hostility, naivety and vulnerability. Puccini incorporated dramatic energy with substantial amount of lyricism, with choruses, recitatives, and arias woven seamlessly together, making it known for being “thoroughly-composed”.
