On Oct. 23, 1964, the world welcomed future bass god Robert Trujillo and years later the musician has been responsible for laying down the low end on some of rock and metal's great tracks. This Readers Poll reflects on Trujillo's musical history and asks you to name your favorite song that he's been a part of.

While many know Trujillo these days for his work with Metallica, the bassist got his start with the thrash outfit Suicidal Tendencies and split his time for many years between ST and their funk metal side group, Infectious Grooves. Over time, Trujillo built his reputation as one of rock's great bassists and that led him to several great opportunities.

He spent the early 2000s as part of Ozzy Osbourne's band and also appeared on albums from Alice in Chains' Jerry Cantrell and Black Label Society. He also lent his talents to Glenn Tipton's 'Baptizm of Fire' solo record in 1997 and was part of the collective Mass Mental? in the late '90s. The flurry of late '90s and early '00s activity caught the eye of Metallica, who eventually chose him as their bassist after the exit of Jason Newsted.

In retrospect, it's amazing to think that Trujillo has been a part of everything from Suicidal Tendencies' 'Institutionalized' through Metallica's 'Broken, Beat & Scarred.' We've included a "greatest hits" of sorts for Trujillo's career below. Take a look at the selection and tell us which Robert Trujillo song is your favorite by voting in the Readers Poll:
