The Strokes are one of my favourite bands ever, but it's mostly based on Is This It and Room on Fire. I was obsessed with those albums when I was a kid and was a huge fanboy of the band. Everything after Room on Fire has been disappointing for me. Not that their haven't been any good songs after RoF, but the albums pale in comparison imo.
Is This It was a really important album personally. I didn't put a ton of thought into music as a kid past what my friends listened to on the radio or what my mom played in the car but that started to shift after hearing Is This It. Really that and the first Gorillaz album in 2001. Is This It connected me to The Strokes' influences and older rock in general (Velvet Underground, Television, Stooges, Stones, etc.) and Gorillaz had all those collaborations that branched out into different genres like underground hip-hop + Damon Albarn which got me into 90's Britpop (and that led me to even older British music like The Smiths and The Jam and whatnot). Really so much that can be traced back to those two albums.
