It's shocking to see only Gary left from the old days (especially that 3 members have just left in such a short time). Still I'm sure SHKM will be great, because Paul is such an awesome drummer and Lee is a fantastic guitar player (don't know if he contributed to the album, though). My biggest concern is the vocals, but we'll see- as long as they're not hardcore shouting or death metal growling (like in a lot of newer retro-thrash bands), just keeping it old school, it may come out really well.
Nice picture BTW
