Alkaline Trio’s four-day residency at the Troubadour aimed to showcase a cache of rock hits from all eight of the band’s studio albums since its first release in 1998 — and Los Angeles fans ate it all up.

Sunday marks the last night of the band’s L.A. stint called Past Live, which started Thursday. The band plans to play two albums in their entirety each night, keeping an element of surprise for fans by not performing any of the albums in order.

Alkaline Trio, which consists of co-vocalists Matt Skiba (guitar) and Dan Andriano (bass) along with drummer Derek Grant, performed its latest album “My Shame Is True” and bookended the night with its debut, “Goddamnit,” during its first sold-out residency show.

“We’re mixing it up so that hopefully the people that are only coming to just one of the nights get a combination of both new and old material,” Skiba said.

The band started off Thursday with “She Lied to the FBI” off its 2013 album and played right through to “Until Death Do Us Part.”

“This is (expletive) great,” Skiba told the sweaty crowd. “But I will tell you that the newest record is way harder — way harder — than the first record.”

To which the crowd roared as the band went right into its first studio album, which included the acoustic sing-along “Sorry About That” before the band performed its encore and last song, “Warbrain” originally released in 2004.

“It was one of those things where people ask, ‘What albums do you want to see?’ For me, I don’t care. I’m just so stoked to see them play any of their albums,” said Lauren Pepping, 31, of Los Angeles, who admitted this was her first time watching Alkaline Trio since being hooked at 15 years old.

“When I started listening to them, it was definitely as a bleeding heart teenager and they said everything in their music that I couldn’t,” Pepping explained. “Even now, as an adult, it still resonates. In just their ability as musicians to convey emotions and to be able to keep crowds like this — I mean, this is (expletive) incredible. For a band to be around so long and for them to do a residency that’s sold out for all its days is amazing.”

With only a few days to recoup, the Chicagoans-turned-Angelenos will be having a homecoming of sorts when it brings the four-night, eight-album concert series to their native Chicago from Oct. 16-19. They also perform in Brooklyn from Oct. 21-24. All dates through the month are sold out, but Skiba said the band is already thinking about bringing the show to other cities and even overseas.

“I’ve known other bands that have done this concept and I love it,” said 27-year-old Daniel Lewis of North Hollywood. “There are some groups where you just love their entire album and yeah, for these guys, why not go and pay for one night and hear every single song from that album that you love and get to see them perform another album on top of that? There’s nothing better than that.”

Elizabeth Geske, 49, who traveled with friends from Napa to catch the only California residency by Alkaline Trio this month, couldn’t agree more.

“I’ve followed them for a long time and love their music,” said Geske, who has seen the band live nearly a dozen times and hasn’t gotten tired yet. “They always perform awesome; I’ve never seen them not great.”

Still riding the success of its 2013 album, “My Shame Is True,” which was well-received by fans and critics for its catchy hooks and classic punk riffs, a new album is inevitable for the band — Skiba jokes the band can never sit idle too long.

Until then, however, Alkaline Trio’s focus is on its Past Live residencies.

“Right now we’re trying to not lose our minds learning and remembering 100 songs, some of which we’ve never played live,” Skiba said.

The Los Angeles News Group chatted with Skiba before the band’s L.A. residency to talk about the band’s lofty concept and its longevity:

Are you guys still riding a high off of “My Shame Is True”?

Skiba: We are. It got such a great reception from fans that it doesn’t really feel like a “new” record or have the usual new record curse where it takes people awhile to warm up to it. The fact that people seem to dig it so much, and the fact that we did it with dear friend and hero Bill Stevenson (Black Flag/Descendents/ALL/Only Crime), makes this record really special for us. We’re stoked to play it in it’s entirety for our fans. We’re quite proud of it.

What is Alkaline Trio working on now?

Skiba: We’re discussing taking these shows to other cities and possibly overseas. We do a lot of our writing on the road so I’m sure we’ll be talking about a new record before too long. Sitting still isn’t one of our strong suits.

The band is nearing it’s 20th anniversary; does that freak you guys out?

Skiba: Thank you to our fans! They’re the reason we get to do this (expletive) and yes, we’re freaked out in the best way. We have the best fans in the world. A lot of artists say that, but in this case it’s actually fact.
