Theory of Relativity - Seasoned musicians blend multiple talents
Brad D. Morley
35th Anniversary Edition | February - 2012
The band Theory of Relativity is a group of Portland’s seasoned musicians, grouped together and blending multiple talents to provide one of the town’s smoothest dance and classic rock bands on the club circuit today.

Led by guitarist Jim Crutcher, this band has an extensive song list that includes all the standard songs you know and love and is always sure to pack a dance floor. In addition, there’s a great list of old school classics and specialty numbers that brings even the most jaded Portlandia critics a reason to raise their head and take notice.

A consummate professional, Crutcher holds down the guitar spot, as well as playing saxophone and performing lead and backup vocals.

He is relaxed, moving from song to song with ease and appears to be having a great time as he plays through the bands set. Introduced to music by his mother, Crutcher performed as a child in Alaska, learning his musical chops on an old Suitcase Organ at the age of 8.

The fifth grade found Crutcher learning to play the saxophone at school until his teen years of rebellion found him donning his first electric guitar. Playing in his ensemble keeps Crutcher busy; however he still has time to run a jam night on Wednesday at Tigardville Station. A great club with a house sound system, good food and an owner who is one of the nicest guys in the Portland club scene, you should put this on your schedule for a midweek escape.

Brian Keefer, on guitar and lead vocals, plays center stage in the band. A consummate front man, Keefer has an extensive background playing in bands and has toured the U.S and Canada with multiple groups. Former front man for Portland bands Funktion, Blue Gin and The Redcoats, Keefer has a strong stage personality and comes alive when he is knocking out renditions of classic songs and hits from the King. Performing songs as diverse as Elvis to Paul Revere and The Raiders and Bad Company, Keefer will surprise you when he breaks into a fantastic job of Billy Jean from Michael Jackson. The guitar duties are shared by Keefer and Crutcher in this band and the two gentlemen work together as old friends and pros. They perform classic rock songs where the expectation of skill and old-world wizardry is at a very high level.

Stage left finds Byron Bender on the bass guitar and backup vocals. With over 40 years of playing on his resume, Bender has great walking bass lines and a very solid tone. Born and raised in Beaverton, Bender started his music career playing the trumpet with mentoring by his father. As a student of classical music at University of Oregon, it allowed Bender to have fun playing in jazz projects and big band. He lists his bass influences as Jacco, Jack Bruce and Rocco Prestia. All great bass players have a Fender in the arsenal somewhere. Bender cites the Fender line as his go-to for bass, as well as his electric and acoustic guitar.

A legend in the music industry, Eric Donaldson Tworivers, sits on the drum throne. A true pro that the Portland music scene is lucky to have, Tworivers played for 20 years in the Dick Clark production band; this man has earned his wings. Need chops? He’s got them, for any gig and any style of music. Tworivers is a trained Arthur Hull Down drum circle facilitator, as well as a REMO Drum Circle artist. He currently accepts students and runs drum clinics to keep busy when he is not keeping time on a stage in the Northwest club scene.

Theory of Relativity is a pro band with a great live show and song list for any occasion. As well, the band performs theme shows for your enjoyment at weddings or private events. The band also has a CD available for sale on CD BABY titled Common Man.
