Tune in this Tuesday at 8 p.m. for WMSE’s Local/Live — this week’s guest is Mathew Haeffel. This Milwaukee singer and songwriter performs acoustically-driven, worldly pop. Solo, or with his five-piece backing band, Haeffel is a busy performer, playing nearly one hundred dates per year. Last year, he released his first full-length record, Rhythm Ethics and has been promoting that effort with shows throughout the Midwest. To hear Haeffel’s infectious and upbeat music and see what’s on his plate for 2011, tune in this Tuesday at 8 p.m. 91.7 FM on your radio dial or stream, live at WMSE.org.
