Hannes Grossmann, drummer for progressive metal bands OBSCURA and BLOTTED SCIENCE, has just released his first instructional DVD, "Progressive Concepts For The Modern Metal Drummer", a two-DVD-set that features almost four hours of material. The DVD is available at HannesGrossmann.com.A six-minute DVD preview clip can be seen below. Commented Grossman: "The DVD is appropriate for beginners, intermediate and advanced drummers. I wanted to show my specific practice concepts, but also give an insight into combining different styles with death metal drumming — like I do in OBSCURA. So the DVD also features a lot of music performances of OBSCURA, but also others, like Ron Jarzombek. It was a lot of work but I think it was definitely worth it." "Omnivium", the new album from OBSCURA, sold around 2,000 copies in the United States in its first week of release. The CD landed at position No. 11 on the Top New Artist Albums (Heatseekers) chart, which lists the best-selling albums by new and developing artists, defined as those who have never appeared in the Top 100 of The Billboard 200.
