TJ Thomas


I owe my passion for music and drums to a fat man in a red suit one late December morning in 2005 when I awoke to a sparkly red 4 piece kit.  Actually it was my dad, who got me into this craziness, but I am so thankful he did.  The kit that the aforementioned fat man brought me has since been swapped out, and has grown quite a bit over the last 13+ years as has my continued love for music.  I have been fortunate to have had the opportunity to start gigging on a regular basis at the age of 14.  My nearly 10 years on the road has given me the opportunity to play all over the city of Pittsburgh as well as a lot of regional work in the rest of PA as well as WV and Ohio on regular basis.  Those opportunities have afforded me the pleasure of sharing stages with Lady Antebellum, Charlie Daniels, Brett Eldredge, Aaron Tippin, Sammy Kershaw, Diamond Rio, Lindsay Ell, and LoCash to name a few.  There’s not a day that goes by that I don’t find myself behind my kit trying to hone my craft.  Although most of my career has been within the country genre, I have a love for metal and classic rock which is evident when you see my 9 piece kit with the old fashioned rotos at one of our shows. Some of my biggest influences in music include Mike Portnoy (Dream Theater), Neil Peart (Rush), Alex Bent (Trivium), and Daniel Erladsson (Arch Enemy).
