Adam Rey / Guitar and Vocals

I received my first guitar when I was 13 from my dad. Since then, I have played in more bands over the years than I can even remember!  I ended up moving to Reno 1n 1988 because I needed more steady work than L.A. was providing for me. I ended up meeting a Fusion/Jazz group called 'Tsunami' in Mammoth California who was looking for a guitar player........... Well, that is how I ended up in Denver when I joined those guys. They were established in the Denver 'smooth jazz' scene so we played all over for festivals, clubs, parties, e.t.c. At the same time I was developing other connections and was busy freelancing with other groups in Denver also. I hooked up with a local producer/musician named Lance Bendikson. We recorded one album (Radio Kings) as a group and did a ton of studio work with the various artists that LB produced. Doing all that studio work was a tremendous time of growth for me as a musician and I am very proud of the work that came out of that time.

Tim Greenhouse / Piano, Keys and Vocals

I started playing the piano at age seven following in my brother and sister's footsteps. My father, a Julliard trained classical violinist, taught me piano at the beginning and I went on to study with many great teachers including Artur Stoyunov, a fantastic classical pianist who had defected from the Soviet Union and emigrated to the U.S . I, at my fathers advice branched out into jazz and pop etc . Early in my musical career I participated in the prestigious Montreaux Jazz in Switzerland. Lots of fun! From there I have continued playing in clubs , private parties , etc . I've played with everyone from Lannie Garret and Hazel Miller locally to Bob Hope. I play all styles of music.
