YOU must be doing something right when not one but two rock legends are singing your praises.

Deadly duo Deap Vally – vocalist/guitarist Lindsey Troy and drummer/vocalist Julie Edwards – play King Tut’s next Tuesday, August 29, having just spent several weeks touring the USA with Blondie and Garbage.

And the Los Angeles pair impressed Blondie singer Debbie Harry so much she was even helping them with their make-up before heading onstage.

“Everyone on that tour was cool and fun to hang about,” says Lindsey.

“I knew Shirley Manson beforehand and I got to know the rest of the band, who were all such inspiring people. Then Blondie are the most iconic band you can think of – Debbie Harry ended up doing my make-up a couple of nights on tour!

“Everyone got to know each other. Shirley is a really big fan of our band and was great at telling us that the band was special and we needed to keep going. That really lifted our confidence, and on the first night of the tour Debbie came over and was asking all about the guitar parts, and complimenting us. It was pretty wild to have that all going on.”

It’s deserved for the band, who have released two albums of in your face rock n’ roll, with last year seeing sophomore record Femejism coming out. The duo have big riffs and biting tunes with lashings of attitude, so it is no wonder Shirley, Debbie and company were impressed.

However they arrive in Glasgow off the back of a surprising release – an acoustic EP called Femejism Unplugged, that presents stripped back versions of a few songs from last year’s album, complete with added saxophone.

“It was a whole new set of challenges trying to make these songs sound big while unplugged,” says Lindsey.

“Julie played with brushes for the first time and ended up loving it, and I was playing an acoustic guitar all the time. It was reminding us a bit of the Violent Femmes as we went along, where you can play acoustic and still make it rock. So a song like Grunge Bond was still really rocking, then something like Turn It Off had a Leonard Cohen type of feel to it, which was completely different to anything else.”

Glasgow, however, will see the pair turning up the volume again.

“We love Scotland because it’s always such a good time,” adds the singer.

“It always feels real there, there’s no pretentiousness. It’s all about having fun and we love it – we actually had the tour booked then added the show on because we realised we hadn’t played Glasgow in a while.”

The band aren’t afraid of making big decisions, as they decided to risk doing it on their own for the second album, walking away from a major label with Island Records. And Lindsay’s hoping she can inspire the next generation of female musicians too, displaying how it’s possible to do things your own way and still succeed.

“Representation is so important,” says Lindsay.

“I wouldn’t be doing this today if it wasn’t for my role models growing up like Hole and seeing Courtney Love rock out, or even a band like No Doubt with Gwen Stefani. That is why representation is so important, because if you see someone that looks like you you’ll be going ‘oh, I can do that!’, whereas before you’d think it would be impossible.”

That doesn’t mean life is straightforward, especially on an independent label. But the singer is relishing the highlights when they happen.

“I try to be grateful for everything we have, because this is a crazy business,” she adds.

“Sometimes it’s so unglamorous and then at other times, like the Blondie tour, it is so glamourous. At those points you just have to enjoy every moment of it.”
