Sonic Elements is a unique American Progressive rock project formed in Los Angeles, California, in 2011.  Led by musician and sound producer Dave Kerzner, Sonic Elements is a new type of "fantasy rock tribute band" where some of the elements are authentic parts of the original music, whether it is one of the original musicians from the band or vintage instrument sounds recorded by the original recording engineer/producers.  Sonic Elements takes samples produced by the sound design company Sonic Reality Inc and puts them into musical context, creating a virtual "super group" per song that combines different musicians with Sonic Reality sampled drummers and more. The 16 Deadly Improvs are an American improvisational progressive rock band based in Madison, New Jersey.  They record and release music through their own label, Rosemont Recordings.  They're noted for their unique sound which combines the elements of "traditional" improvisational blues and jazz with the "non traditional" styles of heavy metal, ambient, progressive rock and electronica.  The majority of their music is performed together live in a studio without any prior rehearsals or sharing of musical thoughts before the recording process begins.  This gives their recordings an overall warm organic feel that creates a completely refreshing listening experience.  Although the band rarely plays live in front of an audience, they've been known to perform one-off shows over the past 15 years. Joe Lynn Turner (born Joseph Arthur Mark Linquito, August 2, 1951) is an American singer, guitarist, songwriter, and producer.  He is known for his work in the hard rock bands Rainbow and Deep Purple.  During his career, Turner fronted and played guitar with pop rock band Fandango in the late 1970s; and in the early 80s, he became a member of Rainbow, fronting the band and writing songs with guitarist, Ritchie Blackmore and bassist, and producer, Roger Glover.  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.  In 2006, Frontiers Records approached Turner to become involved with the AOR side project Sunstorm.  By 2016, four albums under the Sunstorm name had been released.

Elevado earned a Grammy award in 2000 for his work recording and mixing contemporary R&B recording artist D'Angelo's critically acclaimed album "Voodoo".  "Voodoo" is now considered a classic album in the contemporary R&B genre and paved the way for the neo soul movement.  Elevado's "old school" engineering techniques and preference for using mostly vintage equipment gave the album a sound reminiscent of classic soul or funk records fused with hip-hop textures and psychedelic treatments heard on classic 1960s and 1970s rock records.  In 2015 he and D'Angelo won another Grammy for Best R&B Album for his work on D'Angelo's "Black Messiah", the long-awaited follow-up to "Voodoo".  Also notable is his work with The Roots, Erykah Badu, Common and Bilal.
