What are “Thunderbox,” “Dogstar,” and “P,” and what distinction links them?

All three are forgettable rock bands…all of which could count as a member a huge movie star of the day. (Sort of like how Academy Award nominee Jared Leto took half a decade off from acting to record and tour with his alternative rock band 30 Seconds to Mars.)

• Once a successful star of action and martial arts movies, ‘90s star Steven Seagal now spends most of time on other pursuits: being filmed working as a policeman on the reality show Lawman, but mostly his music. He’s written and performed songs for three of his own movies, and he’s released two blues-inflected rock albums, Songs from the Crystal Cave and Mojo Priest. Thunderbox is the name of his backing band, with which he’s toured Europe and the Americas.

• Dogstar was formed in 1991 by drummer and TV bit actor Robert Mailhouse when at a Los Angeles grocery store he befriended a bassist who also dabbled in acting, some guy named…Keanu Reeves. They recruited two more members and by 1995, the band was touring the U.S. and Asia, opening for Bon Jovi and David Bowie. Dogstar graduated to headlining its own club tour, with ultimately very popular bands like Weezer and Rancid opening for them. Dogstar never had a hit song, but they did play England’s Glastonbury Festival and released two albums before Reeves (never the lead singer) left the band in 2002.

• P is the shortest-named band in history, but is also notable for being a collaboration between Gibby Haynes (front man for the Texas punk band the B******* Surfers) and some guy named Johnny Depp, before he was an A-list superstar, and back when he was primarily known for starring in quirky movies like Edward Scissorhands and Ed Wood. P played most of its gigs at The Viper Room in Los Angeles, which Depp co-owned. P released a self-titled album in 1995, which produced a minor radio hit: a cover of ABBA’s “Dancing Queen.”
