Tom DeLonge and his estranged Blink-182 bandmates Mark Hoppus and Travis Barker continue to plow ahead on very separate trajectories. Today (March 24), the Blink singer-guitarist unveiled “The Invisible Parade,” a second, acoustic track from his upcoming solo debut, a collection of demos entitled, To the Stars… Demos, Odds and Ends. Watch the lyric video -- which features DeLonge roaming town with a guitar slung over his shoulder -- above.

“The Invisible Parade” follows To the Stars’ lead single, “New World.” The album is slated for an April 21 release. What’s more, DeLonge tweeted that he has another four albums in the works, and he intends to release them all this year:

Meanwhile, Hoppus and Barker recently made their live debut with DeLonge’s replacement Alkaline Trio’s Matt Skiba at a show in L.A. They then appeared at Barker’s Musink festival this past weekend.

DeLonge, Hoppus and Barker have been in the midst of a public feud ever since the Blink bassist and drummer announced they would appear at Musink with Skiba in DeLonge’s stead, saying the one-time guitarist had no interest in touring or recording new music with the pop-punkers. DeLonge then argued that he never quit the band, while Hoppus and Barker later called him “disrespectful and ungrateful.”
