Josh Lautenberg hails from Montclair, NJ and moved to Colorado in 1991. He started playing drums at 10 years old and grew up playing in a variety of bands that introduced him to a wide range of musical genres including rock, swing jazz and fusion. He played in a band in highschool called Aces High that focused on all the current hits of the time: Journey, Van Halen, Bon Jovi, AC/DC, Led Zeppelin, Whitesnake, Motley Crue. 

While laying down the beats for Aces High, Josh was also playing with a jazz fusion band (with no name) lead by Michael Eisenstein, who is currently the lead guitarist with the band Letters to Cleo. In high school, Josh and Michael favored tunes by bands like The Pat Metheny Band, Weather Report, Allan Holdsworth and more. Fusion is where Josh learned to develop an adherence to tempo and lyrical drumming. 

In college, Josh played in a classic rock jam band that blew the roof off of every fraternity on campus. 
After moving to Colorado, Josh joined a bluegrass band for a short stint before becoming the drummer for Rewind, a local cover band in the Vail Valley. Rewind took Josh back to his roots with Aces High as they cover all the hits from the '70s and '80s. 
​
Now the drummer for the newly formed rock band, Quadrasonic, Josh has arrived at the pinnacle of his drumming career as he is thrilled to be laying down the beat for this incredible band. 


Mark Roebke received his first ‘real’ guitar as a gift at age 4, but never got the chance to really play it because he broke the neck off rocking out next to a wall! By middle school he was in a band with neighborhood buddies, and would practice at night under the covers of his bed to avoid annoying his parents. In high school, Mark grew his hair as long as his mom would allow and played guitar in his school’s favorite new wave/punk band, performing at school dances, backyard parties and mall parking lots.

While studying mathematics in college, Mark switched gears to heavier rock, bigger amps and even longer hair. His influences are a blend of old school shredders (Edward Van Halen, George Lynch) and modern metal bands (Black Veil Brides, Bullet for My Valentine, Polyphia). In addition to music, Mark has enjoyed a ‘career’ as a nationally-ranked mountain bike racer and, professionally, as a technology entrepreneur with multiple businesses in the outdoor recreation space. He does not have any interesting hobbies like gardening, pottery or reading.


Guy Sedillo bought his first guitar at the age of 11 from a Sears Outlet store with money received as Christmas gifts. He promptly started taking lessons and has parlayed those lessons into an over 40 year love of playing live music. He played in heavy metal garage and backyard party bands in high school and many more rock and roll bar bands after drinking age was achieved.  

Always a guitar player he has always had a fascination with the bass. His first bass gig was playing in the Jr. High School stage band. After a serendipitous encounter with drummer Josh, he picked up the bass again and earned a spot in Quadrasonic for his second ever gig on bass. 

A native of of the Los Angeles beaches, Guy has lived in the Vail area of Colorado since 1993 and still goes surfing when visiting his hometown of San Pedro, CA along with skiing, snowboarding, mountain biking, hiking and skateboarding in the mountains of Colorado. 

He brings his hard rocking energy and the thrill of a rekindled instrument to Quadrasonic.
