I have been to his concerts and also I went to New York City to see him perform in "Evita". This is his foundation site: "http://www.rickymartinfoundation.org/", although he is a very successful artist he takes the time to help those kids who need it. In the site you will find the latest things that the foundation has done for the kids, the people who invest in it, why Ricky decided to start it in the first place, etc. This is a quote from him about human trafficking: "You are not alone. We are with you. Put a stop to discrimination. Put a stop to hate. Put a stop to racism...Long live love, long live peace". The official site is this one: "http://rickymartinmusic.com/Home, where he has a blog, the ultimate news and performances, where he is going to go next, etc. Apparently he has a lot of fans in Australia because I found a facebook page that the name was Australian's friends of Ricky Martin: https://www.facebook.com/AustralianFriendsofRickyMartin.
you find there pictures from her, the latest articles written to her, the awards she has won or has been nominated. She has all types of songs but I listen to her when I want to sing my heart out and when Im feeling kind of sad. She doesn't have a foundation but she appeared in "el teleton" to help those in need. http://www.teleton.cl/noticias/natalia-jimenez-y-chino-y-nacho-en-teleton-2012/, that is the article that was written when she made the appearance. Also when I went to her concert she made the announcement to send a text message to help the oncologic hospital of Puerto Rico, so she is an artist that is aware and concerned of the problems of the people.
As many artists she has a facebook page made from her fans, https://es-es.facebook.com/NataliaJimenezClubOficialDeFans. There you can see photos uploaded from her daily activities, next performances, fans writing to her, etc. As I said earlier I almost cried when I went to her concert, it was awesome. This is a quote from the band she was in "La quinta estacion": "No me hables de volar, prefiero caminar y así salir de ésta con vida...", from the song "Sin salida".
And last but not least, my other favorite artist to listen is: Rihanna. The kind of music she sings is for when you want to get pumped up about something, like for example when you are in the gym, or on you're way to a pop, etc. I've never been to a concert of her unfortunately, but I love almost all of her songs. They are good to dance. Her official site is: http://rihannadaily.com, there you find the ultimate news of the artist, the dates and places of her next performances, clips of some of her songs, she even has a part of fashion where she uploads photos of her in outfits and tells her fans the designer and the price.
She takes the time to help ill children and made a foundation named Believe, to help them. The site of the foundation is this one: http://www.believerihanna.com, but it is under construction. The article that talks about some concerts she has done for charity and the price to the tickets is this: http://www.looktothestars.org/news/656-rihanna-performs-for-the-believe-foundation. Apparently in Costa Rica she has a lot fans because, she has a facebook page that the name is: "Rihanna Costa Rica club de fans", https://www.facebook.com/Rihanna.CostaRica.
