Depending upon how the recording is done, there can be much low frequency information below 60hz in modern rock recordings. Metallica's Lars Ulrich tuned the Tama kick drums for the "...And Justice for All" album down in the 40hz range. There is a serious amount of lower end bass there. Not to mention it was a fairly decent recording to boot with good dynamic range. Not everyone's cup of tea I know, but it prove's Sheep's point.
Tool has a lot of content below 60hz on nearly all of their albums. Danny Carrey (drummer) uses a truely impressive kit that allows for some impressive low end, especially on the "Undertow" and "10,000 Days" albums. Many of their songs bass sections are played in the Low "E" key as well.
Korn is another rock band known for their low tuned kick drums and bass. I am sure there are many others.
I have a couple Jazz albums that have a lot of low end below 60hz as well. Burt Conrad AllStars "A Soulful Journey", Fourplay "Between The Sheets" & Boney James (unsure of album) are just a few that come to mind.
I have the Sennheiser HD212 (not an extremely linear headphone, I know) but they easily play into the 30hz range.
