Mikael from Opeth - fantastic, both growls and cleans
Mikael from DT - again fantastic, although more high pitched, his cleans are good too, if a bit gothic style
Tomas from ATG - raw and energetic, I like him. Actually I think he would somehow fit older In Flames if Anders wasn't around
Nillo from Insomnium - really deep growls and they don't remind me of DT's Stanne. His singing might sound unintelligible and sometimes dull, but it fits Insomnium music perfectly. I like his singing.
Peter from Hypocrisy - Apocalypse unleashed upon Earth
Anders - his singing was basically yelling on TJR. On that Koln concert you can see he's struggling a bit and losing his growl on a few occasions. Whoracle was a better. Then came Colony where he really shines! After that Clayman and RTR sounds like he's starting to lose his voice a bit. STYE was OK again, CC not bad. ASOP and SOAPF, struggling to find a sustainable voice. Too much processing and layering since year 2000.
