I just can't get into DEP. Mudvayne are my hometown boys and they still play a lot of local shows when they can. I remember when they first started out and they were touring the same local metal scene I was at, they certainly looked different during the early days:)
Messhuggah has gotten weirder over the years. Right around the onset of the "Gothenburg Sound" which was heralded by bands such as In Flames, Messhugah started going into very lengthy epic types of music that employed 8 string guitars to makes things more layers without sacrificing heavy. However, I can't say their current foray into more experimental stuff is heavier than their older material. I last saw them when they toured with Tool for the Lateralus album.
