Keyboardist Erik Deutsch is back in Boulder to perform music from his upcoming release This Was Then. In between touring the world with rock legends The Black Crowes, recording the grammy-nominated album Happiness Bastards, and performing non-stop in his hometown of Mexico City, Deutsch has found time to produce his 9th solo record and present a sneak peak of the&nbsp; new music before the official release in mid-July. Joining him for this special 2-night engagement at The Muse will be ace drummer Michelle Pietrafitta and rising star Hunter Roberts on bass along with long-time collaborators Bill Kopper on guitar and Jonathan Stewart on saxophone.&nbsp;
