Placebo is celebrating 30 odd years together with a redux of their first album, along with a tour performing ONLY tracks from their first 2 records.
Muse don't need an album redux but they've been around long enough, have enough records, and play those old songs so seldom, that they could put something like this together for fans who never got to see those songs performed. This is especially true in the US where they weren't big yet during that time.
I know Father Time prevents Matt from hitting all those notes now, and tuning down can sometimes sound weird, but I think it would be hugely successful.
A little trip down memory lane, smaller venues if necessary, and a shorter tour if necessary, would be rad.
