At Nashville’s Ocean Way Recording Studios on this warm spring afternoon, you could sit in Studio A next to Grammy Award-winning producer Bill Vorn Dick at the 80-channel Neve 8078 soundboard and see some of Music City’s most respected musicians before you. Drummer Doug Belote, guitarist Guthrie Trapp, and bassist Todd Parks lay down the beat; on the far side, visible behind glass in twin isolation rooms, the session leader, dobro wizard Jerry Douglas, and guest vocalist Travis Tritt play off of each other in a version of “Marriage Made in Heaven.”

Tritt dominates the performance, his singing laced by Douglas with a long counter-melody, as the band negotiates the changes like the Michael Jordan—era Bulls moving downcourt, locking together and turning the Paul Brady song into a paragon of musical teamwork.

So smooth is their blend that Luke Bulla’s fiddle works almost subliminally until, maybe halfway through, it becomes his turn to fill around Tritt’s soulful singing. And then it rises, staying in its low-to-middle range, with a line that stretches languorously, its tone sweet and rich, before settling back into the mix.

All of this happens in a windowless booth behind a door at the back of the console room. Only when the take is wrapped does Bulla emerge, dressed in jeans, windbreaker, and T-shirt, his thick-framed glasses, upswept hair, and disarming good looks suggesting that James Dean had come back, with a fiddle in is hands.

“When I was younger, I definitely fell prey to the temptation to play fast,” he says, reflecting on the process of creating parts based more on substance than flash. “We used to call it ‘jam-busting.’ It had its place in that it helped everybody think a little faster. But as you get a little bit older, you learn to exercise restraint, and that can be even more challenging.”

Bulla, 28, speaks and plays with the wisdom of experience, as well as the enthusiasm of youth. He came to Nashville in 1999 with a stellar record in competitions, having taken first prize six times at the National Oldtime Fiddlers’ Contest in Weiser, Idaho, in whatever age category he fit at the time, before becoming the youngest winner of its Grand Championship at 16. Bulla also distinguished himself at the Grand Master Fiddler Championship in Nashville, becoming, at age ten, the youngest participant ever to finish among the Top 10 finalists.

Even before then, he was a seasoned performer, having joined the Bullas, his family band, as a singer when he was four years old. They were based out of Washington state, in a rural stretch of the North-west not known as a hotbed of musical talent. He and Jenny Anne, his younger sister by 13 months, studied violin together, graduating from Suzuki training to private instruction with Sandy Roney. Mostly, though, they traveled with the Bullas, playing twin fiddle parts or switching to guitar or mandolin on their way to a pivotal encounter with bluegrass fiddle legend Bobby Hicks.

The Bullas were in Greensboro, North Carolina, visiting Luke’s grandparents, when they dropped in at a local music store, the Music Barn. Hicks happened to be there; after hearing Luke and Jenny Anne, he promised to mention them to bluegrass star Ricky Skaggs, in whose band he was playing at the time. Through a sequence of coincidences, Skaggs heard the Bullas and invited Luke to tour with his band, Kentucky Thunder. Playing together and alternating solo parts with Hicks, Bulla made his mark in Nashville while also expanding beyond the Texas style of playing that had been his stylistic touchstone.

“Texas fiddle music is a bit slower,” he explains. “It’s like western swing, but the long-bow style makes it much more even, with lots of eighth notes and single-bows. With Ricky, I was playing straight-ahead bluegrass at breakneck speed. It was definitely intimidating.”

Today, as a member of Douglas’ band and through his work with Béla Fleck, Edgar Meyer, Bryan Sutton, and other like-minded players (including as one of the Scrolls, featuring members of Tom Petty & the Heartbreakers, Elvis Costello and the Imposters, Nickel Creek, and others), Bulla has found his place at the forefront of acoustic-music innovation. Whether imparting what he’s learned as a teacher at the annual Mark O’Connor Fiddle Camp or applying it to writing material for his anticipated solo album debut in early 2009, his mission is to keep expanding his horizons without neglecting the roots from which his musicianship has grown.

“I’m getting older and have more real-life responsibilities, which make it harder for me to put in the time to practice,” he says. “So I’m going back to some fundamentals. I’m working on scales and doing shifting patterns, working on etudes and studies from some Carl Flesch books, and talking with a friend of mine about theory and jazz improvisation. It’s a challenge, but it’s exciting too.

“It’s all about challenging yourself and always finding another level to move onto.”
