Melissa Etheridge, the Grammy-winning singer/songwriter who has produced enduring hits like “Come To My Window” and “I’m the Only One” during a music career that spans 25 years, will bring her unique brand of authentic heartland rock to the Longwood Gardens Open Air Theater for a show on Aug. 25.

Etheridge is currently on a 50-date tour promoting “This is M.E.,” her critically acclaimed 12th studio album, which was released in 2014, and the DVD “A Little Bit of Me: Live in L.A.,” which was released two months ago. The tour concludes at the end of August, and has included everything from solo performances to full band concerts to festival stops to co-headlining shows with rock legends like Blondie and Joan Jett.

Etheridge has been showcasing some of her new songs songs like “Take My Number,” “Monster,” and “A Little Bit of Me,” as well as her classic hits like “Come To My Window,” “I’m The Only One” and “Bring Me Some Water” during the current tour.

She also continues to be one of the most open and honest voices in music. She openly came out in 1993, and has been an advocate for gay rights ever since. She has also spoken openly about her struggles with breast cancer and her use of medical marijuana, and she has always lived a public life with grace, dignity, and confidence.

Etheridge has been nominated for 15 Grammy Awards, winning two, in 1993 and 1995. She also won an Academy Award for Best Original Song for “I Need to Wake Up,” which was featured in the film “An Inconvenient Truth” in 2007. She was also honored with a star on the Hollywood Walk of Fame in 2011.

If you can’t catch Etheridge before the current tour ends, the DVD “A Little Bit of Me: Live in L.A.” captures the singer and her band at the height of their powers during a performance at the historic Orpheum Theater in downtown Los Angeles.
