[Machine Translation] Keiko Iwasaki, organizer of the jazz live bar and school "Piano CUUB," released the CDs "Keiko Iwasaki with DREAMERS" in 2016 and "Keiko Iwasaki Collection 2 with DREAMERS featuring Marika Hiraga" in 2017. After releasing "Keiko Iwasaki with DREAMERS" and "Keiko Iwasaki Collection 2 with DREAMERS featuring Marika Hiraga" in 2017, she produced a CD for school students and those learning jazz vocals to practice vocals with backing in actual live performances and concerts. The demo vocals feature Lorna Cifra ( lead vocalist of the previous two CDs), Naoki Yamasato, and Marika Hiraga, and are performed by the same backing, allowing students to learn rhythm, pitch, nuance, and other elements. The karaoke features male and female keys so that more people can practice their singing.
