If the forecast predicts rain on Earth Day, never fear: You can still commemorate nature while staying dry. The Tarrytown Music Hall hosts the Hudson River Sloop Clearwater’s second annual Earth Day Benefit Concert on Sunday, April 22. Janis Ian, Tom Paxton, Toshi Reagon, and Lucy Kaplansky join a number of other notable artists to create a musical evening in honor of our planet. All proceeds will aid Clearwater’s environmental education and camp programs. Tickets are available for individual purchase ($48-$125) or through two sponsor packages ($250, $1,000), which include access to the sound check and a post-concert reception, among other special perks. 7 p.m. 13 Main St., Tarrytown. 877-840-0457 or www.tarrytownmusichall.org
