Vocal Chords is from Dale Earnhardt Jr. Jr.’s album It’s a Corporate World. These guys have a great sound that backs up the quirky name they chose for the band. Dale Earnhardt Jr. Jr. played SXSW last year and will be performing again this year. They will also be playing at the Bonnaroo Music and Arts Festival if you want to catch them there. Checkout their website to see other tour dates.
Thanks @thinkjose for turning me on to these guys.
