In other words:

Regarding the recording of Move Like This: “It was hard not having Ben around. There were many, many times when we all missed him. I remember when we used to do background vocals, for instance – and it was usually Ben, Greg and myself standing around a mic – so during those times on this record when we did background parts, it felt very strange not to have Ben there. There are so many other things, too – his sense of humor, his bass playing… He was just a great guy. Everything about him, everything he did…it was all missed.” — Elliot Easton, musicradar.com, April 18, 2011
