Melissa Lou Etheridge (born May 29, 1961) is an American singer-songwriter, guitarist, and activist.
 Her self-titled debut album "Melissa Etheridge" was released in 1988 and became an underground success.
 The album peaked at No. 22 on the "Billboard" 200, and its lead single, "Bring Me Some Water", garnered Etheridge her first Grammy Award nomination for Best Rock Vocal Performance, Female.
 In 1993, Etheridge won her first Grammy award for her single "Ain't It Heavy" from her third album, "Never Enough".
 Later that year, she released what would become her mainstream breakthrough album, "Yes I Am".
 Its tracks "I'm the Only One" and "Come to My Window" both reached the top 30 in the United States, and the latter earned Etheridge her second Grammy award.
 "Yes I Am" peaked at No. 15 on the "Billboard" 200, and spent 138 weeks on the chart, earning a RIAA certification of 6x Platinum, her largest to date.

 Skin peels back layers of Etheridge's pain and addresses her personal melodrama, as she takes the listener through the stages of grief and recovery.
 "Heal Me" features background vocals by Laura Dern and Meg Ryan.
 Etheridge plays almost all the instruments and penned all the songs.

 The song debuted on the "Billboard" charts after the first week of its release, reaching #25 on the chart.
 It was also the second song from Etheridge that earned her a Grammy Award for Best Female Rock Vocal Performance.
