"Neil Young is considered the godfather of grunge, which is fair. He rocked hard. He still rocks hard. He loves distortion. He has a weird facial hair pattern. He checks all the boxes. But the thing that's always amazed me about Neil Young is that for all of the chaotic grunge energy that powers him, he's never sloppy. Even live. Like on Live Rust, his album with his on-again, off-again backing band, Crazy Horse. The performances are raw and electric, but also amazingly tight. The energy is palpable, but it's all under control. And you wouldn't think that would be the case, given it's a live album of a live album. It was filmed and recorded during the tour for Rust Never Sleeps, a studio album that was recorded live in front of an audience, much like a 1970s sitcom, but without the nitrous oxide-induced laughter."
"Powderfinger" is the first song of the second, electric, side of Rust Never Sleeps. Allmusic critic Jason Ankeny describes the song, following the album's mellower, acoustic first side, as "a sudden, almost blindsiding metamorphosis, which is entirely the point — it's the shot you never saw coming." The lyrics are the posthumous narration of a young man who attempts to protect his family against an approaching gunboat. He realizes that all of the older men are unavailable, leaving him "to do the thinking". After initial indecision, he eventually takes action, and is ultimately killed. He describes his death with the gruesome line "my face splashed in the sky."
"Thrasher" was written while filming Human Highway in New Mexico with Dennis Hopper. Young remembers in a 2022 post to his website: "After leaving Taos with Carpio, a Native American friend I had met during the filming of Human Highway, sitting in the front seat of his car, I wrote this song, "Thrasher". Driving through the magnificent beauty of New Mexico, the words just kept coming to me. I saw the eagles circling, the deep canyons, the road ahead, reflecting on my journey through recent years, and thankful to be where I was." The song's music bears similarity to Young's previous song "Evening Coconut," which he wrote about his boat. In the song's lyrics, he uncharitably describes his CSNY bandmates as "dead weight." Young explains in a 1985 interview: "Well, at that point I felt like it was kind of dead weight for me. Not for them. For me. I could go somewhere and they couldn't go there. I wasn't going to pull them along, they were doing fine without me. It might have come off a little more harsh than I meant it, but once I write I can't say, 'Oh, I'm going to hurt someone's feelings.' Poetically and on feeling it made good sense to me and it came right out. I think I'd be doing a disservice to change it based on what I think a reaction would be. I try not to do that." Young chose not to perform the song for several years after its initial release, due to his reaction to a particularly harsh review of the song. He would tell a 2014 audience "This song, you know, I did it, I haven't done it that much in my life because at a very vulnerable moment I read something about it. Just like the worst fucking review I've ever read. So for all your reviewers, if you feel like your words don't mean anything, you're probably right, but in that case, in that case they were damaging. So, anyway, I think I got this, I think this it's the one here. I hope so."
"He says that when he first wrote the song, he wrote 126 verses to it. Young: "Now, you can imagine that I had a lot of trouble figuring out what four verses to use... I was underneath the stairs at the time... Anyway, this verse that I wrote... It was the worst verse of the 126 that I wrote. So, I decided to put it in the song, just to give everybody a frame of reference as to, you know, what can happen. What I'm trying to say is, by stopping in the middle of the song, and explaining this to you, is that... I think it's one of the lamest verses I ever wrote. And, uhh...it takes a lotta nerve for me to get up here and sing it in front of you people. But, if when I'm finished singing, you sing the chorus 'Sugar Mountain' super loud, I'll just forget about it right away and we can continue." He then continues with the "worst verse", about being "underneath the stairs... And [...] giving' back some glares, To the people that you met, And it's your first cigarette".
"Live Rust is a live album by Neil Young and Crazy Horse, recorded during their fall 1978 Rust Never Sleeps tour. Live Rust is composed of performances recorded at several venues, including the Cow Palace near San Francisco. Young also directed a companion film, Rust Never Sleeps, under a pseudonym "Bernard Shakey", which consisted of footage from the Cow Palace. The CD version of the album was slightly edited to fit on a single compact disc, which were limited to 74 minutes at the time this album was first issued on CD. In 2014, a remastered, high-resolution download was made available on the Pono store, restoring the album to its original length. Between tracks 2 and 3 on side 2 there is a stage announcement calling for people to get off of a tower and comments on an ongoing rainstorm. This is actually taken from Woodstock, almost a decade prior where Young performed as a member of Crosby, Stills, Nash & Young."
