Anyone whoโ€™s ever known (or, worse, dated) a music snob knows the old refrain:  music on vinyl just sounds more authentic. Let them rhapsodize on and itโ€™ll start to sound as though youโ€™re discussing fine wine โ€” LPs have a sound thatโ€™s rich, deep, velvety, full. But hold on a second. Scott Metcalfe is someone who should know โ€” heโ€™s the director of recording arts and sciences at the Peabody Institute of Johns Hopkins. And he says he โ€œdefinitelyโ€ prefers CDs. It turns out that the physical limitations of vinyl โ€” its grooves and pre-set disc size โ€” mean that dynamic range often gets reduced. CDs are, simply put, a more useful technology for capturing a wide range of sounds and frequencies. But what about vinylโ€™s much-vaunted โ€œdepthโ€? Metcalfe has an answer to that:  โ€œIn some cases, the depth of field, the depth of sound that people talk about, enjoying about vinyl that they say is missing from the CD may, in fact, be a result of the compression to make that old recording more competitive for the modern market.โ€ And CDs trump even MP3s, Metcalfe says โ€” โ€œthereโ€™s a loss of depth of field in a smaller formatโ€ฆ Occasionally, Iโ€™ll hear somebody playing, you know, through a PA system at a party or, you know, a reception or something from an MP3, and itโ€™s almost painful for me to listen toโ€ However, Metcalfe does grant that old-fashioned records do allow for a more ritualistic listening experience.

Meanwhile, over at the University of Maryland researchers have found that the stateโ€™s immigrant population makes a substantial contribution to our economy, especially in the science, information, and medical fields. (Twenty-seven percent of the stateโ€™s scientists are foreign-born!) Which is good news, as more than half of the growth in the stateโ€™s workforce was due to foreign-born workers. (The national average was 45 percent; in Maryland, it was a full 57 percent.) Nearly 14 percent of the stateโ€™s population is foreign-born, which is slightly less than Texas, but more than Arizona and Virginia, and about one-third of those live in or around Baltimore. According to the study, immigrants tend to be clustered either in high-income groups or low-income groups, which is one reason theyโ€™re a boon to the economy โ€” they complement the pre-existing labor force. The relatively unskilled immigrant labor force, which is concentrated in the agriculture, seafood, construction, personal services, and tourism industries, also helps out:  โ€œWithout the influx of foreign-born workers, expansion in these labor-intensive industries would have been choked off, increasing prices and discouraging growth across the economy,โ€ the report says. In all, the studyโ€™s authors urge lawmakers to think twice about leaving immigrants and their children out of education and state services plans: โ€œMost of foreign-born young people in Maryland, regardless of [legal] status, will make up a substantial part of the productive, tax-paying work force in a few short years. We will also depend on them to be informed voters and capable leaders so we can maintain strong and dynamic communities throughout the state of Maryland.โ€
