“Krajnyak sings with assurance and has a sweet rock voice that can register sincerity and emotion, but it is in his watchful, physical, discerning performance as Sam that he grabs your attention and respect.” 

- Neal Zoren, Delco Times

APR 8,

I got to sing with my old friend, the wonderfully talented Anna Giordano at Don't Tell Mama. We sang a set of 12 covers and mash-ups, spanning everyone from Maroon 5 to Taylor Swift to Avril Lavigne. I even got to do some arranging. Thank you to everyone who contributed to our amazing (and SOLD OUT) evening! 


For the month of January, I spent some time recording vocals for new metal band, Quantum Twilight. The eight tracks I worked on were amazing - serious video game music vibes. Quantum Twilight's debut album is due for a release later this year. Stay tuned! 

DEC 18,

I directed Siren & Sailor Theatre Co.'s annual reading of A Christmas Carol with a spectacular cast of professional actors. 

OCT 31,

(Mc)Things got a little spooky in October. Joining a wonderful cast of Broadway veterans (including Tony Award nominee Craig Bierko), I took part in a staged reading of Mrs. McThing, a fun romp about the magic of love and family. Directed by Karen L. Carpenter and music directed by Michael Levine, Mrs. McThing was the perfect way to spend Hallow's Eve.
