Every Wednesday at 9:13 am, one of Pittsburgh's finest music writers joins me (Cindy Howes) on the Morning Mix to play a couple favorite new songs and share some insight. Today we welcome Andy Mulkerin of Pittsburgh's City Paper. In case you missed it here's what he played with commentary by Andy: Bear's Den, "Agape": This trio from London opened for Mumford & Sons and also brought along a banjo. The difference was, Bear's Den (yes, another animal band name) didn't try to play to the last row. Instead, the group pulled us in with tender, beautiful harmonies like you hear on this song from the new EP, also titled "Agape." Bill Callahan, "Spring": This guy is no stranger to the indie scene. He worked for 15 years under the name Smog before becoming a solo artist in 2007. His new album, "Dream River," is some of his best work, and should be all over Top 10 lists at the end of the year. This song, which has touches of Marvin Gaye soul, is indicative of his honest and assured delivery.
