Sometimes it’s best to let an artist speak for themselves, as is the case with The Walkmen’s Hamilton Leithauser on his new solo work: “Knockin’ Heart” is sung by an estranged, stoned lover on their way home, who is dying to get a message through to someone who is probably not listening. It is ‘I will love you for life if you’ll let me.’ I wrote and recorded it one evening and put it away for over a year. I knew I liked it, and I didn’t want to mess anything up by trying to perfect it. It was the last song I played for Aaron when we got together, and the first song he helped me work on. I’d say he raised the ceiling and lowered the floor on the entire thing sonically. He actually used a funny bass technique he said he’d used on a Taylor Swift song, which I got a kick out of. I gotta say his bass sounds fantastic. Now there are three basses on it! One of mine and 2 of his. That is a first for me.”
