Love is in the air this weekend, and you'll find celebrations of heavy metal, jazz, plants (both native and illegal), bad-a** cars, social justice through dance, and even an updated opera that puts a new spin on seduction, passion and guilt. Keep reading because there's a "Whole Lotta Love" going down in the Bayou City.

It's a story about immigrants and politics, about clashes over culture, race and equality. One look at today's headline news and the narrative sounds familiar, but Ragtime — based on the book by E.L. Doctorow — is actually set a century ago. Three seemingly disparate experiences weave together with real historical figures in this musical portrait of early America, presented in Houston by Theatre Under The Stars. Ezekiel Andrew, a veteran as Harlem musician Coalhouse Walker Jr., returns in the pivotal role with book by Terrence McNally, music by Stephen Flaherty and lyrics by Lynn Ahrens. With a cast of 25, just about everybody in the audience will be able to identify with something in this upbeat look at the power of tolerance and understanding.

Performances are scheduled through April 28 at 8 p.m. Fridays and April 26, 2 and 8 p.m. Saturdays, 2 and 7:30 p.m. April 21, 7:30 p.m. Monday through Wednesday, and 2 p.m. April 28 at the Hobby Center, 800 Bagby. For information, call 713-558-8887 or visit tuts.com. $30 to $104.50.

Rolling Stone named Led Zeppelin the heaviest band of all time, and there's no denying their dominance in the '60s and well into the '70s. It's a 50th anniversary celebration over at Houston Symphony, and who better to conduct Music of Led Zeppelin than Brent Havens, a composer/arranger with credentials a mile long and who also conducted symphonic rock programs for the Doors, Pink Floyd, the Eagles, Queen, Michael Jackson, The Who, Whitney Houston, The Rolling Stones, U2, Journey, Elton John, David Bowie and Prince. Zebra frontman Randy Jackson has a deep well of songs from which to choose when he takes the stage on vocals, though we're burning candles for "Whole Lotta Love," "Stairway to Heaven," "Black Dog," and "Ramble On."

A performance is scheduled for April 19 at 7:30 p.m. Friday at Jones Hall, 615 Louisiana. For information, call 713-224-7575 or visit houstonsymphony.org. $39 to $99.

Don't expect superficial themes of lollipops, fluff and rainbows. Interdisciplinary duo Brother(hood) Dance! have in the past created dance works that focus on freedom and incarceration, the challenges of being gay in a heteronormative climate, and a multi-sensory exploration into those who were lost to the global AIDS epidemic. Next up is a new evening-length work making its world premiere in Houston and presented by The Pilot Dance Project. Hawa (The Ride) takes us on a mythical journey with two horsemen, Jacko and Cavalier Spirit, in this Afro-neo narrative of resilience, discovery and transformation.

Performances are scheduled for April 19 through April 21 at 8 p.m. Friday and Saturday, 5 p.m. Sunday at MATCH, 3400 Main. For information, call 713-521-4533 or visit matchouston.org. $15 to $20.

Sometimes it's better to just tell the truth, and with a besmirched reputation Dona Anna (Ailyn Pérez) learns that lesson the hard way in Don Giovanni. Houston Grand Opera is coproducing this updated production with the Royal Opera House Covent Garden, Gran Teatre del Liceu, and The Israeli Opera in this surprising new interpretation that comes with a few surprises, including the finale. HGO Studio alumnus and bass-baritone Ryan McKinny is the charismatic Giovanni, intent on adding another notch to his belt; while tenor Ben Bliss makes his HGO debut singing the role of Anna's noble fiancé Don Ottavio, blinded in his steadfast loyalty for his betrothed. With music by Mozart, libretto by Lorenzo da Ponte, direction by Kasper Holten, set by Es Devlin and video by Luke Halls; the opera is sung in Italian with projected English translation.
