Susumu Hirasawa (平沢 進 ) (born April 1, 1954) is a Japanese musician and composer.  In the fifth year of elementary school, Hirasawa took up the electric guitar, inspired by the surf and instrumental rock bands he heard on the radio and on TV, later joining his junior high school's band.  In 1973 he formed Mandrake, a progressive rock band that incorporated elements from heavy metal and krautrock.  Being one of the few Japanese progressive rock bands of its time, Mandrake achieved little success and released no albums during its lifetime.  After discovering punk rock and working on synthesizer-heavy projects, Hirasawa felt that progressive rock became just for entertainment and decided to reform the band as the electronic rock band P-Model in 1979.  Originally met with success, they turned to decidedly uncommercial post-punk and experimental rock after Hirasawa went through an averse reaction to his fame.  With Hirasawa at the forefront, the band went through various lineups and achieved some popularity in the Japanese independent music scene. The following is a list of artists who have released at least one album in the progressive rock genre.  Note that individuals are included "only" if they recorded or performed progressive rock as a solo artist, regardless of whether they were a member of a progressive rock band at any point.  For instance, Robin Trower never again performed in a progressive rock style after his departure from Procol Harum, so he is not listed here.  Rick Wakeman is, because he recorded a number of solo albums in a progressive rock vein.  Individual band members who have never recorded solo, such as John Myung of Dream Theater, also are not listed. Joe Lynn Turner (born Joseph Arthur Mark Linquito, August 2, 1951) is an American singer, guitarist, songwriter, and producer.

After Rainbow had disbanded (the first time) in March 1984, he pursued a solo career, released one album, Rescue You, and then later did session work, singing background vocals for the likes of Billy Joel, Cher, and Michael Bolton.  On the advice of Bolton, Turner began recording jingles for radio and television.  Other songs he had composed or through collaboration with songwriters like Desmond Child and Jack Ponti were being recorded and released by international recording artists Jimmy Barnes, Lee Aaron, and Bonfire.  Turner had a short-lived association with neoclassical metal guitarist Yngwie Malmsteen and then Deep Purple.  From the mid-1990s, he resumed his solo career, releasing an additional nine studio and two live recordings.  Turner did other session work, appearing as lead vocalist on tribute albums and working on projects involving various musical groups including progressive rock band Mother's Army; Bulgarian hard rock band Brazen Abbot; funk rock duo Hughes Turner Project; and classic rock/ progressive rock band Rated X.
