Mentioned in Kerry's first "Tech Tuesday" blog post on 2009/09/15 as part of a run-down of mics used to capture Mike's drum sound:

In front of the drum kit and about 4 feet away is a Telefunken Elam 251 (this particular microphone is very famous it was used by Steely Dan to record a lot of vocal tracks and it also works really great to capture the mid range and low end elements of the drums in the room.)
