Gabriel Mark Hasselbach’s album Tongue & Groove on Mesa/Bluemoon earned him his 11th Billboard hit with Chill@Will (featuring Bob Baldwin), and now “Litmus Test” (ft. Daniel Seguin) is being released into the wild and going for an even dozen at Billboard! This ‘intricately simple’ song features Gabriel on his sassy/saucy/sexy flugelhorn, Daniel Seguin on alto sax and rhythm programming, Tony Seville on percussion, and Tony Moore on drums.
