Iconic singer Nina Simone and New Jersey rockers Bon Jovi lead the 2018 class of Rock and Roll Hall of Fame inductees, which includes four first-time nominees.

The Cars, as well as first-time contenders Dire Straits, The Moody Blues and Sister Rosetta Tharpe, also are part of the 2018 class announced Wednesday. They will be inducted on April 14, in Cleveland.

The six inductees were chosen from a group of 19 nominees, including Radiohead, who were expected to enter in the Rock Hall in their first year of eligibility, but didn't make it.

Tharpe, a pioneering guitarist who performed gospel music and was known to some as "the godmother of rock 'n' roll," will be inducted with the "Award for Early Influence." She died in 1973. The other five acts will be inducted as performers.

The jazzy and soulful Simone, who died in 2003 and was also a first-time nominee, was a leader in pushing for civil rights and influenced the likes of Alicia Keys and Aretha Franklin.

The Cars, founded in Boston in 1976, combined New Wave and classic rock sounds. This year marked the band's third nomination.

Bon Jovi, first nominated in 2011 and again this year, has sold more than 120 million albums and launched No. 1 hits with "Livin' on a Prayer," ''You Give Love a Bad Name," ''Bad Medicine" and "I'll Be There for You."

Rock Hall voters have recently opened their hearts to progressive rockers, which benefited "Nights in White Satin" singers The Moody Blues. English rockers Dire Straits, which includes brothers Mark and David Knopfler, blended blues into their music.

Each year, five to seven acts usually make it into the Rock Hall following a vote by 1,000 people, including performers, music historians and industry experts. Fans also were able to vote on the Rock Hall's website. All of the inductees had to have released their first recording no later than 1992 to be eligible.

The 33rd annual Rock & Roll Hall of Fame Induction Ceremony will be held at Public Auditorium. Tickets will go on sale in January and the event will later air on HBO and be heard on SiriusXM Radio.
