On this board I see a couple of interesting threads on these records, about it's major flaws or best moments. Reading them made me also realize (again) that we are in a new PJ era.
If backspacer poses a question, is Lightning Bolt its answer?? In my opinion 'S/T' was the answer to 'Riot Act' in many ways, you could say it was PJ's political era.
But I don't think 'Backspacer' poses any questions. It's basically an exclamation mark. It's the record where they choose to have some fun. As Stephen Thomas Erlewine (allmusic) puts it:
There was nothing to be answered. PJ's is reinventing themselves now. When you selftitle your record it always means something. It means: 'this is us, and this is what we do best, cause we have been doing this for years!'. Backspacer is the adding to that by saying: 'But hey! We can have some fun too!!'.This means, all things considered, Backspacer is a party record for Pearl Jam -- a party that might consist of nothing but philosophical debates till the wee hours, but a party nonetheless -- and if 18 years is a long, long wait for a band to finally throw a party, it's also true that, prior to Backspacer, Pearl Jam wouldn't or couldn't have made music this unfettered, unapologetically assured, casual, and, yes, fun.
'Lightning Bolt' sounds like a question mark after an exclamation mark. Basically they said in interviews that it was the logical extension to Backspacer. That is true with songs like: Getaway, Mind Your Manners, Sirens, Lightning Bolt, Sleeping By Myself, Swallowed Whole, Let The Records Play, Future Days. The problem is that those add less to their catalogue, it's not answering Backspacer, it's following it's footsteps. Future Days is the sequel to 'Just Breathe', but the latter was better executed. Both 'Supersonic' and 'LTRP' are fun filler tracks written by Stone. Unthought Known sets the premise to 'Lightning Bolt'(song). With 'Getaway' and 'MYM' they even answer some questions from the 'political era'. In my opinion 'Lightning Bolt' only leaves us with four songs that cover new ground: My Father’s Son, Infallible, Pendulum, Yellow Moon. These songs don't answer anything they are posing another question. Pearl jam has made confusing records before (No Code, Binaural) but those always covered new ground for the band althought on thin ice. I consider 'Lightning Bolt' the first truly transitional record the band has ever made. Not confusing because you're entering new territory but because you have no idea on where to go next. In a way it's like The Who's 'face dances', 'Tattoo You' by 'The Rolling Stones'. or 'Life' by Neil Young & Crazy Horse, 'Human Touch' by Springsteen or 'End hits' by Fugazi and some more. The problem with 'transitional' records is not that there are no question or exclamation marks, it's that there are warning signs.
The band is reinventing themselves and it could very well be that they have no idea where to go next. Things could stay the same and will get another logical extension of Backspacer or thing could change, more power to Jeff or different producer etc...Either way, it's an uncertain time...so: achtung! achtung baby!!
