(FILES) In this July 23, 2014 file photo, singer Mariah Carey attends the premiere of « Hercules, » at TCL Chinese Theatre in Hollywood, California. Carey has put out two full Christmas albums but now has gone one step further with a series of holiday concerts, which she hopes to turn into an annual event. The inaugural extravaganza featured a dancing Santa, a 10-foot (three-meter) tree and a half dozen happy child performers. The six-night, sold-out residency, which runs through December 22, 2014, takes place at an unusually intimate venue for the superstar — the 2,900-seat Beacon Theatre. Sunday’s crowd ranged widely in age and nationality and included — in relatively understated attire — younger pop diva Lady Gaga, who wrote on Instagram that Carey sounded « legendary. » AFP PHOTO / ROBYN BECK / FILES
