The US band TROUBLE started in 1979. On their first three records("Psalm 9","The Skull". "Run To The Light") they mixed BLACK SABBATH with the period of NWOBHM. In 1990 they released the self-titled album, that is still one of my alltime faves. It's more 70's like, but still very heavy and the following two records ("Manic Frustration","Plastic Green Head") continue this way. TROUBLE influenced many bands (Metallica etc.), but like all the other bands here they always were some kind of an underground act. Loved by musicians and fans but a very bad support from fuckin' record labels. It seems in the late-90's as if TROUBLE broke-up and some members had done several projects like LID, WET ANIMAL or SUPERSHINE. Now in 2002 they are back together and we're waiting for a new album.
In Sweden in the early 80's a band named NEMESIS started out. They released one dark and heavy album, titled "The Day Of Retribution". In 1985 they changed their name into CANDLEMASS and the classic "Epicus Doomicus Metallicus" album created the term Doom-Metal. CANDLEMASS put something new to the Sabbath-based sound and they produce a music that you can call (if you want!) Epic-Doom. In 1986 Messiah Marcolin joined CANDLEMASS and bandleader Leif Edling had the perfect singer. They put out a lot of great records like for example "Tales Of Creation", one of my faves. In the 90's CANDLEMASS split -upand in 1999 Leif Edling released with new members the fantastic album "From The 13th Sun" and now Messiah Marcolin is back again and maybe there will be a new album in the future. Meanwhile he left the band and Rob Lowe is the vocaliust.
Another important Swedish band is STILLBORN. Formed in 1984 they released in 1989 the outstanding "Necrospirituals" LP. One of the darkest rock records that I've ever listen to. Forget bands like Type O Negative, this record is the perfect missing link between BLACK SABBATH and SISTERS OF MERCY. After the first one they released another two records, where they have altered their sound, but I think "Necrospirituals" is the original masterpiece. In the 90's STILLBORN changed into COLOSSUS with Messiah Marcolin on vocals. But that doesn't worked out and the last news are that they have given up the name COLOSSUS, so nothing is certain.
For me all this bands, with BLACK SABBATH on top of it, are a formative influence on todays Doom Metal breed. If you don't know them, go to your record dealer and ask for it. Of course, there are more great bands like REVEALTION, DREAM DEATH/PENANCE, INTERNAL VOID, SOLITUDE AETURNUS, MILLARCA etc. which haven't found their way into my small column.
