Stuff akin to Glenn Branca and Rhys Chatham?

Arnold Dreyblatt - Animal Magnetism has some of the same kind of euphorically repetitive, ringing strings in just intonation, if more stripped down. It also has more of a groove and some fun horns mixed in. Maybe a little closer to some of the earlier, rhythmic Branca like "Indeterminate Activity of Resultant Masses."

There are moments on Godpeed You Black Emperor's Lift Yr Skinny Fists... that almost pastiche Branca. On the whole, I think it may be a stronger composition than any of GB's although it doesn't really have the ecstatic moments that derive from the sheer massed sound of GB's guitars.

Fred Frith's guitar quartets (try Upbeat) do somewhat different things with the sound of 4 electric guitars. The interplay and sonic variety is pretty dazzling.

For a more ambient approach, you could try Garlo's Vent de Guitares, where massed numbers of guitars in different tunings were just left out on a windy cliff in Europe and recorded.

Also, if you don't know these pieces, some old Ligeti has some similar sonic qualities even though it's not done with guitars. I like "Lontano" a lot myself.

Never really saw the appeal of Band of Susans myself but it's been close to a decade since I tried.

I know you really like this record, so I'm not sure why you used the word "pastiche", but Branca is faithfully xeroxed many times on the album, absolutely.

Some of Caspar Brotzmann's noisier moments sound not unlike a one-man Glenn Branca ensemble, ditto Rudolph Grey.

Scott, most Rhys Chatham is worth picking up. Die Donnergotter is like a Krautrock interpretation of Branca (tho to be fair Chatham got there first and Branca learnt his tricks from him). One of the best (and loudest) concerts I ever saw was the final performance of Die Donnergotter at CBGBs. There are quite a few other nuggets strewn throughout his discog. For an academic minimalist's take on punk/rock (which was his stated mission back in the late 70s) it's pretty cool stuff.

Then we're in agreement over the Branca/GYBE similarities.

Poss + Stenger were in Chatham's band at that final Die Donnergotter performance.

When I saw GYBE in '99 I thought, "Great, this is like a Branca chamber ensemble!" So, yeah, the comparison is apropos. They were playing mostly Skinny Arms material at that point.
