Lost and Found Sound presents a story about present-day uses of the most ancient of recording technologies: the wax cylinder. On the occasion of this month's release by trumpeter Wynton Marsalis's album of wax cylinder recordings, we hear what it is about wax that appeals to some. For Marsalis it's the authentic sound, which reminds him of the jazz greats of the past. Also featured: Les Paul and the band They Might be Giants. John Flansburgh of the "Giants" learns that to get recorded, he has to stick his head into a brass cone and sing in a very pronounced way.
