"If you spend any time looking for records at flea markets and garage sales, you come to recognize a variety of common vintage records: Herb Alpert & the Tijuana Brass, Barbra Streisand, box collections of "best of" classical music, the band America. And then there are the rare finds, the albums that you would never expect to exist. My latest find at the Alameda Point Antiques Fair falls into that category ... it became my possession for $2. And now yours, via SoundCloud, for nothing." Sounds of X-15s, Atlas missiles, Nieuport biplanes, and more.
