Hey Teacher... Leave Those Kids Alone!
Ready for an ultrasonik graduation tour?!
Leave Those Kids Alone features talented teenagers performing note-for-note renditions of classic rock favourites. “Hey teacher!” This ain’t no noisy garage band, these kids are alright!
Audiences from across Ontario, the U.S., and a worldwide online audience love hearing LTKA’s renditions of chart-topping hits. If you’ve played it on vinyl or heard it on the radio, Leave Those Kids Alone will make it rock… LIVE!
Based in Windsor-Essex, Ontario (born and raised in “South Detroit!”), LTKA is a go-to act for summer concerts series events, annual festivals, public gatherings, corporate engagements and even weddings! Through their online videos of classic rock hits, Leave Those Kids Alone has reached every corner of the world earning millions of views!
Brother-sister duo of Alex (guitar) and Addi (drums) are paired with Luca (bass) and Louis (keyboards).
In May 2025, the band released their second all-original album, titled Mach One, under a new name… ultrasonik. Shifting to this name solely for original music will see the band form a new identity which celebrates their songwriting efforts vs. Leave Those Kids Alone’s celebration of classic rock hits. All classic rock tribute live shows will continue as Leave Those Kids Alone… though with the success of ultrasonik’s Mach One you are likely to hear a few of their original songs as well!
Formed in 2018, the band has performed over 350 shows and are no strangers to events with 5,000+ people in attendance! This summer’s 40+ performance dates have been labelled “The Graduating Tour” as Leave Those Kids Alone fully transitions to ultrasonik in 2026, featuring their originals and an all-new repertoire of rock hits from EVERY era! (As always… stay tuned!)
Now entering their 8th season of shows, the band maintains a tireless performance, rehearsal and online video production schedule to reach audiences in-person and around the world.
