I just seen them in Guelph, Ontario last June. Awesome show, great performence all round, some songs were kinda sloppy, but that's the nature of the band during performance(Adam D. In particular). The departure of Howard sucks, he's definitely my favourite of the two, that being said, Jesse Leach is still an amazing singer.
KSE was the band that got me into the heavier side of metal. before that the heaviest i listened to was metallica and now im into the more prog/technical side of metal (meshuggah, animals as leaders, vildhjarta, veil of maya, etc)
adam d is still has one of the best stage presences of any guitarist though
Howard was okay, I didn't like most of the songs he did though. Not my style. With that said, if all metal sounded the same, I would probably hate metal.
