Gossip Wolf has long hailed the virtuosic string shredding, herculean productivity, and synergetic programming of Chicago's Spektral Quartet. During the COVID-induced absence of concerts, violinists Clara Lyon and Maeve Feinberg, violist Doyle Armbrust, and cellist Russell Rolen have continued to engage their audience via a series of Zoom Q&A sessions called New Music Help Desk. In keeping with the quartet's collaborative sprit, previous events have included composers Alex Temple, Allison Loggins-Hull, and Chris Fisher-Lochhead, and the next one features Pulitzer-winning Chinese composer Du Yun. It's on Friday, March 5, at 3 PM, and though it's free to attend, you must register at Spektral's website.
