Sleep is a stoner metal band that has barely changed over the years and I love them for that. They've only made four albums plus some singles. Their first three albums, Volume 1, Sleep's Holy Mountain, and Dopesmoker came out in 1991, 1993, and 1999 respectively. Dopesmoker is a 1 hour album comprised of only 1 song, or one 60 minute song plus a bonus song depending on the version. Then they didn't make another album until The Sciences in 2018. Trust me on this, The Sciences sounds so incredibly similar to their first three albums it's kind of crazy. It's just more modern, the bass hits heavier, and it's noticeably better produced.

It's amazing to me that they were able to come back all these years later and produce such a similar sound while still exploring new ways to make that sound.
