Andy Milas


I am not a jazz guitarist, or a rock guitarist, and definitely not classical. I am a person that loves to listen to Progressive Rock and Metal, New Age, Jazz, Greek and Middle Eastern music and tries to bring all the elements together as a composer and a guitarist. After two decades of playing, performing, studying, writing, and arranging for all those different styles I still love listening to bands like Fates Warning and Metallica, which were the reason why I wanted to start playing music in the first place. Of course over the years artists like Michael Hedges and George Winston, Avishai Cohen and John Zorn, Simon Shaheen and Laco Tayfa, Porcupine Tree and Tool, Al DiMeola and Strunz and Farah, and so many others have all left their mark on my playing and my compositional style.

Esthema is my attempt to take everything I know and love about music and fuse it into one. I sincerely hope everyone enjoys.

Tom Martin


Solid, feel, pocket, and ears. These are the words Tom recalls hearing most from other musicians about his playing. Over the last 15 years his solid pocket, strong ears, and strong work ethic has earned his reputation as a premier bassist and first call sideman.

Tom has a theory that people are like musical notes. Each has their own frequency and there are limited frequencies. Putting those frequencies together creates a chord and each person affects the overall "tone" of the group. Though a rhythm person at heart, Tom thrives on harmony and the possibilities different people can create. Pursuing the possibilities is what Tom enjoys about making music.
