Tanya O’Callaghan is an established freelance musician / bassist, speaker and activist with an eclectic impressive career to date.

Tanya began making a mark for herself on the Irish music scene early in her career, always playing with multiple Irish bands at once and regularly guesting in house bands for many high-profile Irish TV shows.

Never afraid to make a leap of faith, Tanya’s determination, passion and talent began to pay off the further she spread her wings internationally. She has toured, recorded and written with legends such as Whitesnake, Bruce Dickinson (Iron Maiden), Maynard James Keenan (Tool/APC), Dee Snider (Twisted Sister) Steven Adler (Guns N’ Roses) Nuno Bettencourt (Extreme), The Riverdance, The Voice, Orianthi, Michael Angelo Batio, Kevin Godley, Sharon Corr (The Corrs) and David Grey, to name a few…

While the Irish rhythm technician is known for powering through propulsive rock and metal tempos, her dynamic talents extend far beyond any single genre.

A whirlwind of energy, positivity and determination, it’ll come as no surprise that Tanya is also a speaker, writer and lifelong advocate and activist for animal, human, social and environmental issues. A force to be reckoned – it’s fair to say that this Irish lass has made her mark on the music scene both at home and internationally!

“Tanya O Callaghans bass playing has – como se dice en Espanol.. The Balls!”

Maynard James Keenan / (Tool, A Perfect Circle, Puscifer)

“What an amazing experience it is to know & work alongside this enchanting woman…Irish born & bred, she simply owns the groove…& makes it look & sound effortless, while her drive, enthusiasm & inspiration is an absolute blessing for all of us in Whitesnake…

A captivating, electrifying live performer she delivers every single show…I have nothing but the highest praise for Tanya. She is deserving of all the success that comes to her & to those who have the pleasure to work alongside her

Simply the best…”

David Coverdale / (Whitesnake)

“Yeah, yeah, Tanya O’Callaghan (or TKO as I like to call her) is a girl – No shit Sherlock. What gave it away? But that’s not why she’s in my band. She’s my bass player and MD because she crushes it (and more than a few bass amps) every fucking night!! In two words…TKO ROCKS! “

Dee Snider / (Twisted Sister)

“I have been so lucky to play and tour with Tanya, it’s rare for me as a drummer to find such a bass player to lock in with, who has swing and also rocks, pockets and groove for days, I am blessed to play with her”

Steven Adler / Guns N Roses

“Tanya has such a distinctive and engaging playing style, her live performance and presentation is so unique and very entertaining. Great player and more importantly, a great person.”

Billy Sheehan / (Mr Big, David Lee Roth, The Winery Dogs)

“Tanya is a pleasure to work with. A wonderful bass player, gorgeous vocalist and great fun to have around. She has a unique sense of her own style both musically and fashion wise and therefore has a huge stage presence!”

Sharon Corr / (The Corrs)

“A super talented bass player. She is not only technically strong but more importantly, all artists want her in their bands because of her sense of feel and pocket. She has the the most sought after quality as a musician… RESPECT for the song. You also have to know how to perform with your instrument on you, not just play it. The physical side to the stage is underrated. Tanya is a great performer and fun to watch.”

Nuno Bettencourt / (Extreme, Rhianna)

“Tanya’s deep talent involves bringing the dirtiest, funkiest, or most thoughtful and delicate bass parts to tracks that don’t know what kind of bass they need. She has an unnerving knack for searching out and applying the perfect musical glue and that’s her specialty.”

Kevin Godley / (10cc, Whole World Band)

“I had the pleasure to work with Tanya O Callaghan in Ireland on the 2011 Preacher’s Son album that I was producing. I was delighted with her playing and impressed with her abilities. Her musical skills are strong and her versatility is remarkable. I would definitely hire her again for other projects.”

Marc Urselli

“Tanya O Callaghan is a wonderfully talented musician. Her natural ability to hold down the bottom end, lock in with the kick and simultaneously support the melody of a song is incredible. Also an amazing live performer Tanya is one heck of a force to be reckoned with!”

Warren Huart / (Aerosmith, The Fray, James Blunt, Daniel Powter)
