That pic is from when Brien Stewart brought his band the Key Figures to Alexandria a few years ago. As you can see from the pic, it was a rockin' gig and the guy is an energetic frontman.
Researching some details about his past exploits, I was having a hard time finding online information on his time as singer for D.C. area band Avail. But, in case you forgot, he was the originial frontman of that band.
Now you can download -- for free -- the band's early recordings courtesy of Brien Stewart.
Be sure to keep an eye out for gigs from Brien's current band, Basic Skills Review.
