An Earth Day celebration downtown, an exploration of '90s L.A., a bunch of singing teenagers and more stuff to do or see in L.A. this week all for five bucks or less.

Considering the human race spends 365 days a year obliterating the planet, from the outer reaches of the atmosphere to the deepest depths of the sea, it's only fair that we should spend one of those days behaving like we give a shit. Join fellow contrite beings in Grand Park for the city's annual Earth Day celebration. Activities include yoga and a tour of the park's sustainable landscaping, plus electronics recycling and composting; there are even opportunities to learn about how to be less of a blight on the environment each and every day. It's literally the least you can do. Grand Park, 200 Grand Ave., downtown; Fri., April 22, 9 a.m.-2 p.m.; free. —Gwynedd Stuart

One of the SoCal music education system's greatest triumphs has been the Los Angeles Master Chorale's High School Choir, a rigorous program that includes teacher-led training, rehearsals and master classes for students and choral directors, guided by members of the L.A. Master Chorale. The Los Angeles Master Chorale's High School Choir Festival shows off 1,000 choir students from 31 local schools, joined in song under the baton of LAMC artistic director Grant Gershon and guest Tesfa Wondemagegnehu, conductor of American Public Media's The Radio Choir. Additional performances by the LAMC Chamber Singers and the Festival Honor Choir. Walt Disney Concert Hall, 111 S. Grand Ave., downtown; Fri., April 22, 1 p.m.; free (first come, first served).

The L.A. experience can lead to exhaustion or exasperation — “Let me be, Los Angeles!” — but Will Erokan and Gerry Fialka see it differently. Their psychedelic art party, Let Me Be Los Angeles, brims with musicians, poets and dancers, as well as avant-garde projections splashed across three huge video projection screens. It's what they call a “phantasmagoRIA” (“Resonant Interval Algorythmns”; I know, just go with it) and it channels the energy that issues forth from L.A.'s creative continuum in waves of inspiration, flowing through everyone from Maya Deren to John Cage to Rod Serling. Beyond Baroque, 681 Venice Blvd.; Venice; Sun., April 24, 7 p.m.; free. (310) 822-3006, —David Cotner

Is the Internet Turning Kids Into Zombies? That's the question tonight's Zócalo salon asks, and you'd probably get some really interesting answers from the legions of grieving mothers and fathers whose children have been lost to Minecraft and Periscope. Instead the audience will hear from Yalda Uhls, senior researcher at UCLA's Children's Digital Media Center; High Tech Los Angeles principal Marsha Rybin; and RAND education policy wonk Lindsay Daugherty, who'll discuss concerns over children whose lives are increasingly given over to this latest version of the plug-in drug, and what that means for happiness and productivity in general. RAND Corporation, 1776 Main St., Santa Monica; Mon., April 25, 7 p.m.; free. (310) 393-0411, —David Cotner

Sara Benincasa is a comedian and author of four books, including 2013's Agorafabulous!: Dispatches From My Bedroom, about her struggles with agoraphobia, panic attacks and depression. Her latest, Real Artists Have Day Jobs: (And Other Awesome Things They Don't Teach You in School), is 52 essays of practical advice for artists in all mediums that are “inspired by my 35 years of flaws, fuck-ups, failures and occasional good choices,” Benincasa writes.

Clark Gable and Marilyn Monroe made their last silver-screen appearances in The Misfits, John Huston's tale of a divorcee and two latter-day cowboys. (Rounding out the main trio is Montgomery Clift, whose own untimely end came a few years later.) Largely unsuccessful upon its initial release but now considered essential viewing, The Misfits is one of those movies whose legacy threatens to overshadow what's on the screen — at least until you actually watch it. LACMA, 5905 Wilshire Blvd., Mid-Wilshire; Tue., April 26, 1 p.m.; $5.
