On this day in 2015 we lost Christopher Russell Edward Squire, the English musician, singer, and songwriter best known as the bassist and a founding member of Yes. He was the longest-serving original member, having remained in the band until his death and appearing on every studio album released from 1969 to 2014. Sadly, we lost Chris June 27, 2015 after a battle with Leukemia. He was 67.
In his honor, check out some classic videos of Chris and Yes, including Chris' isolated bass track from "Roundabout" above
